Slingshot Reviews 

Avoid at all costs and do not join this company especially small family house holds will be charged to power a factory and have ridiculous extra costs plus a high gst cost on top off each power bill and charge a paper fee. COMPANY IS REVENUE BASED ONLY

⁰Everytime I pay Slingshot via internet banking they are never able to allocate the payment to my account which results in me getting over due notices. I have been chasing them since 10th July to allocate a $10 payment. It has taken them 3 weeks and multiple emails with no action. I belive they make it difficult on purpose so peole get frustrated and pay via debit/visa/Mastercard which comes with a surcharge, hence gathering them more revenue. It shouldn't take 3 weeks to allocate a simple payment. My bank account is in the same name as my Slingshot account and I used the reference number they requested. Ridiculous!!! I have switched to 2 degrees and find them amazing. Still waiting for them to figure out where my money went and allocate it to my account .....

I've been with with Slingshot for 17 years and I regret ever signing up with them. I've had on and off problems with the Internet the whole time.
However my biggest complaint is with their mobile plan. 2 years ago 2 degrees took over the mobile service. I was offered 100GB free. I took up their offer. Then one year later they took away the 100GB data!! Two years later they are still taking away data. Last month they took away 1 GB of data. This month I've had almost a similar amount taken.

I have been with Slingshot for two years. I decided to move to Mercury because they were much cheaper, only to be slapped with a $250 early termination fee. Only after I phoned and questioned this, did they admit that they'd made a "mistake". Be careful of Slingshot and their underhand practices.

If I could give zero stars, I would.

My experience with Slingshot has been one of the most frustrating customer service experiences I have ever had.

After the passing of my grandmother, I contacted Slingshot to cancel her broadband while keeping the power connected. What should have been a straightforward request turned into weeks of unnecessary stress.

During this process I was asked to provide the same information multiple times, including the account number on several occasions. I also had to resend my grandmother’s death certificate after being advised that it had been misplaced. Despite repeatedly following up by email and phone, I was left waiting for weeks with little meaningful communication.

I lodged a formal complaint and was repeatedly told my case had been escalated, yet I continued to receive delays with no clear timeframe for resolution. At one point I was advised that the only way to keep the power connected was to take out a bundled broadband service at an additional monthly cost, despite my request simply being to close the broadband following my grandmother’s death.

The lack of communication, repeated requests for information that had already been provided, and the way this situation was handled during such a sensitive time caused unnecessary stress and anxiety.

Eventually, after weeks of waiting and chasing updates, I lost confidence that the matter would be resolved in a timely manner and chose to close the account altogether.

I sincerely hope Slingshot reviews how it handles bereavement cases and customer complaints, because no family should have to experience this level of frustration while trying to manage the affairs of a loved one who has passed away.

Terrible company, we had been with slingshot for a few years and our internet would always disconnect periodically, we paid for the fastest upload and download speed yet our internet was still very slow, we had too many issues to the point we switched providers, we gave our 30 day notice today yet they cut off our internet straight away, we are meant to have internet right up until that 30th day when our contract ends, we called up to see what was going on, and since it’s a Friday, they can’t do anything till Monday, so we now have no internet and will be paying for internet we can’t even use? They’re terrible, don’t sign up with them, we had problems with them, and more problems leaving them.

Not recommended at all! I have joined them and have regretted it for several reasons. First, their broadband is weak and disconnects every single time. Second, the power is much more expensive compared to other providers. Third, the customer service is poor. I emailed them and did not receive a response for 2 weeks. Fourth, they have switched my automatic payments to credit card payments without informing me. When I checked my billing for a 2 months, I was charged a credit card fee. I do not even have a credit card. What a ripped off!

Poor Internet with constant drop-outs, and unreliable connection despite promising a strong broadband that would be able to handle multiple devices. Despite these shortcomings, they have offered no explanation, compensation or service in any way. I am currently writing this review using a Hotspot from my phone (different provider) because the internet has dropped out again.

This would have to be the absolute worst company in NZ today ! Emails that bounce back say we don’t monitor this email . Links in emails that don’t link . Appalling customer service. You should be ashamed of yourselves! My advice, do not join!

🤢 Don't even bother - honestly avoid like the plague! 15 + years (we recon more towards 20!) with Slingshot, and as a busy family using them for work and home, we've noticed worse and worse service and customer service and absolutely no inventive or discounts offered freely. We essentially had to fight for any 'deal' they DO NOT value loyalty. Over the last year or so we have had regular drop outs with our land phone line and slow internet and customer service DO NOT CARE... they take your money and don't actually deserve being supported. Now they're taking an extra $250 to finally leave!!! ABSOLUTELY GOOD RIDDANCE.... you will not be missed

For three months they have gaslighted the hell out of us.Internet will go out same time every evening and sporadically through the day.Had new modems provided and also mesh.Waste of time and money!Have made a formal complaint and will most definately change providers.This has been ongoing and we are all over their bullshit.Worst ever!!!

Was yelled at by customer service when trying to ask what was going on with my billing. He had a thick accent I couldn’t understand so asked him nicely to tell me again. He yelled at me and implied I was stupid because I couldn’t understand him. Also they overcharged me for my final month and are refusing to refund me

Slingshot internet is so laggy and crappy charging huge prices for super fast internet and it’s so slow , customer service representative's speak really bad English and don’t know what the hell they are doing, they need people who can speak better English and power prices via slingshot are outrageous !!! This company will eventually fall if they don’t sort there customer service out, you have to repeat yourself a hundred times before they get it’ ridiculous!

Their team really don't know what they doing and how to handle customer query. My account was closed and cleared with Slingshot in 2024 , and they charged $5 in error after closing of account. They sent just one email of invoice, and I never got access to login into my Slingshot account once my account was closed. Few months later in 2025, they sent another email of apologies, saying it was charged in error and we credited your account. Somehow, it took them 6-7 months to realise it was their fault and they entered my account in bad debt for few months. They never followed up, no letter, no email for collection notice, never bothered to correct my credit, or never sent any reminder of anything. I was unaware of any credit Arrears until my refinance application lodged with bank, and they informed me.

This year on 09/01 I contacted and asked them what is wrong with my account. CS team advised Sorry, it was our fault, you will be getting formal letter from our credit team by 14/01/2026, stating it was our error. I didn't receive any letter, I contacted them again on 14/01, they kept me on call for literally 60 minutes. During these 60 minutes, I been transferred 6 times between Customer team, and 3 collection team. 6 different people asked me to verify account details, name and address, and all were saying, our team is not the correct one to help, we will put you thro another team. 2x people gave me conflicting answers, one said it will take 2-3 weeks to get formal letter from us and another one said 30 Business days. I asked them to send me a email if you lodge this as a case, and all they provided with case number only visible to their eyes, no written confirmation of case such as email or message with case number reference sent to my account

I never seen such unprofessional and untrained team in my entire life. Not even for single second I feel, they value customer or they know how their one error impacting someone's life.

THIS COMPANY IS A TOTAL DISFUNCTIONAL COMPANY
MY ELDERLY FATHER WHO IS 87 AND BLIND IS WITH SLINGSHOT
HIS MODEM WAS FAULTY SO SLINGSHOT SENT HIM A NEW ONE, IT WOULD NOT WORK WITH HIS LANDLINE SO HE HAS BEEN WITHOUT A LANDINE FOR 9 DAYS NOW
I HAVE PHONED SLINGSHOT APPROX 30 TIMES WITH NO JOY
THEY DO NOT PHONE BACK AND APPEAR TO MAKE UP LIES SAYING EVERY THING IS WORKING
THE LANDLINE IS DADS ONLY FORM OF COMMUNICATION
SHOCKING SERVICE SLINGSHOT
YOU SHOULD BE CALLED A TOTAL SHAM NOT A COMPANY

Thier new policy on Mobile Carry Over Data Plans.
Your carryover data does not get used first.
They use your monthly Data First and and then use your carryover Data once you monthly Data is used up.
This way your Carryover Data is not renewed each month and every month any Data that reaches the 12 month period is lost (in other wards stolen and re-sold)

Slingshot definitely takes advantage of the elderly, wish we had looked into it before my mother passed away. She was being charges over $100.00 per month just for her broadband, then her power was si expensive, we have now changed companies, after my mum passed they would not cancel the broadband without a death certificate and that takes months to get so they wanted us to pay for a service that we are not using.

Dogshit company, Spent ages getting it setup so i was authorized to talk to them because my parents new nothing. now all of sudden my names not on the list and i cant even talk to them about the account what a joke

Terrible would not recommend this company for broadband.
There service keeps dropping and interrupted then you have 20 different agents that deal with you each time and dosent solve the problem. End up paying the month bill for interrupted broadband. Go elsewhere
