Zusi Limited Reviews 

My advice DO NOT USE this company. I have given one star as unable to leave none.
Sales dept great to set up our new contract and promise the earth. Our restrictions not put in place on the work phones as we requested therefore extra charges and they would not pay the extra charges though they had not done their job properly and this still goes on month after month. Still waiting a week later as to why extra charges on there again. This is the worst company we have ever worked with and regret using them.

Great Company.
Very easy to deal with.
We run a business so we needed a reliable company to provide phone & broadband services, which Zusi does not disappoint.
Internet speed is great, and the phones are much cheaper as they work through the internet.
Great customer service, Zusi keep doing what your doing!

Great service from David.
He was very friendly on the phone, brilliant to deal with.
He sorted out a new contract for us, took a little time but that was down to our prefrence in phones

Abby Leitch Great Service when dealing with a new PC install that required the details transferring over. Always fast and efficient when dealing with any issues.

After speaking to Zusi about our needs, they were able to come up with multiple options that worked for me. The setting up was painless, and I've managed to save a bit each month too! I was dubious based on some of the reviews I read but I've been really happy so far.

Great service from David at Zusi. He sorted out a new contract for us, so quickly. He was very friendly on the phone, brilliant to deal with.

I was sold a great deal by this company, however in reality it has been nothing but stress. Hidden monthly fees, no-one answers the phone to you and everyone I have spoke to has been rude. I wish I had never got a contract out with them and now I am stuck with them for 3 years. Please think twice before using this company, it's been a nightmare from start to finish and please please read the fine print as there is a lot they don't mention on the phone.

Signed up to a Vodafone Contract for 36 months with this company. Line rental £35 per month. £17.50 reclaimable monthly.
They do not pay you back!

Chris and the team at Zusi provide us with great telecoms and service has been fantastic.

Great service from Chris and the team. Really happy with our broadband and mobile services they provide. They are always on hand to offer any assistance needed.

Dealt with Rebecca and Chris for company mobiles and energy contracts. Both very helpful and knowledgeable plus they managed to save me a large amount money. Would highly recommend!

I have had several contracts in the past and present with Zusi and they have always been excellent. Amazing service can’t fault them . Their customer service is impressively quick and customer-focused. They've always been ready to assist promptly.

Dealt with Chris at Zusi to change our gas & elec provider at a rental property, saved us money, service was brilliant and they made the change over so easy for us. Will keep in mind for when other properties are due....
Thanks Chris

Honestly, the worst company I've had any dealings with. After endless calls from pushy salesman for months, we finally decided to place an order for biz sim cards.
At the same time, we discussed broadband and landline as our renewal was due, and they were offering what seemed a good tariff.
Broadband install was arranged for a certain date, they informed our previous provider of the install date. Come the date nothing happened and our previous provided had stopped the broadband and landline. No warning from Zusi of the delay or real explanation, not even an apology! Luckily, our landlord was able to assist with getting us reconnected, but we were without internet and a landline for 4 days. Suffice to say, we cancelled the broadband, only to receive a cancellation invoice for £2.5k, £350 of which was for the cancelled BT visit to install the new line on the amended date, which is completely unjust as nobody was in the office as all staff were working from home!
The landline was diverted to a mobile number so we could at least still receive calls. I’ve asked this to be un-diverted and am still waiting a week later.
We signed a direct debit mandate for the biz sims so assumed monthly payments with the provider would be taken care of, however we received an overdue email from the provider last month, which I queried with Zusi, so then believed this was sorted. We then received another overdue account email this month with a warning that if it wasn’t cleared the provider may restrict our services! Completely ridiculous. As a reputable business that’s been operating for 30 years you do not expect to be in this position.
Communication is poor and the staff seem incompetent (except the sales team!)

TERRIBLE!
Said they'd install the new phone system but then refused! Said I couldn't port PAC codes across then found out I could! Made mistakes in porting the numbers across leading to delays. It's been an awful experience so far. AVOID!

Clear and helpful service
Great customer service explained all options

Got an great deal and made the process really straightforward. Very helpful staff with excellent communication. Will definitely use again 👍

Had a very good experience with Zusi. Staff member was Very attentive and made sure everything went smoothly. Only thing to add would be to quote prices with and without VaT as this caused some confusion.

Abby sorted the O2 Passport out on my phone so that I can use my phone in Australia. This was done in no time at all. Perfect service every time. Thanks

Abby Leitch was very helpful with setting my new office phone up, asked all the correct questions and responded promptly.
