Zusi Limited Reviews 

Daniella is a star and has incredible customer care standards. She is the principal reason we have stayed with Zusi. And she didn't pay me to write this! :-)

I speak to a very friendly lady who is always very helpful and always sorts out any problems I have

No issues and good communication. Set up was straight forward for the VOIP system.

Signed my company up to a contract with hardware fund having been told by the salesperson that the price point would be lower or the same as Apple, now being quoted prices 16.5% higher than Apple.
Wish I had never heard of Zusi.

We have been waiting 12 weeks for a refund of incorrect charges. We are still waiting. We have been told that it is Vodafone holding up the refund. Vodafone are telling us that they are waiting on Zusi. The "Customer Service" from the Zusi Technical Service Manager amounts to "we can't do anymore"

If it wasn't for Daniella this would have been a 1 star review.
Neil Wilson, sales guy is complete liar. Promises the earth and then does nothing.
Daniella worked hard to rectify our working relationship and is a credit to Zusi.

Had trouble porting numbers initially but not he fault of Zusi and they where quick to resolve and no problems since.

I would honestly have given 5 star review had I had no problems
The issue I had arose from the network not Zusi. Whilst my contact at Zusi was incredibly helpful I was without a working phone for a few days.

Great Support from the team, Daniella has been really helpful and responsive in resolving any service issues we have been experiencing.

Sales rep promised many things and we got very poor service. Back up line that was charged for but has never been installed and doesn't work. Intergration with our VPN that didn't work and ended up having to pay for ourselves. Upgraded handsets which were worse than our previous ones. Phones go down no ones availible to help. Avoid at all costs, speaking from experience.

We had the pleasure of Robert Stinton visit our office and apartments yesterday. He switched our data access points over to Zusi from our old provider. He was very professional and incredibly polite, a real pleasure to have him working with us for the day.

Zusi, you have a great asset in Robert!

Our new contract with Zusi began a few months ago. So far so good. We had a small problem with poor reception in part of our building. We mentioned it to Zusi and they didn't get back to us about it. We've raised the issue again, so let's see. Generally we're satisfied.

Initially, we had some trouble porting our numbers, but since then the service has been great. No issues at all; very friendly and helpful staff, periodic phone calls to make sure everything is ok and they are always on top of things, trying to offer the best deals available. We are about to renew our contract, so we hope rates are attractive to continue with Zusi, as we are very happy. Thank you.

SIM card had problems. New card was received within 2 days and problem was solved. Thanks

We were initially assured that the transition from our previous supplier would be seamless, however, the migration proved to be more challenging than expected. The porting of telephone numbers presented a number of difficulties, although these issues were not necessarily the fault of Zusi. I do feel that the transition process and the expectations around it could have been communicated more clearly from the outset.
That said, the support provided by the team has been excellent and is the primary reason I am giving a 4-star rating rather than a lower one. Both Nezaam and Robert have been extremely helpful, responsive, and committed to getting our organisation up and running successfully.
We are still in the early stages of our journey with Zusi, but our experience so far has been positive, and the level of customer support has been particularly impressive.

Abe is a professional Business and sale Manager, he go extra mile to ensure all the IVR telephone features and functionality offered and agreed during the sale discussion are completely implemented, tested and working perfectly for the client. This help the company to give a positive feedback and win more business opportunity for the company. The project is still ongoing but follow up from the sale Manager (Abe) with the technical and support is awesome presently. I trust they we keep-up with this professional awesome standard going forward!.

I would give 0 stars if possible. I’ve got business broadband with them (Trim Fadey). Trying to cancel my broadband and they just go round in circles passing you from one member of staff to the other. Promise you a call back and don’t follow up. Terrible terrible company. Avoid at all costs

I would give is 0 if I could. Promised everything delivered nothing. Constant issues with the phone systems. Support is not there, they promised support 7 days a week but only assist Monday - Friday. They have blocked emergency service calls on our system, which is illegal! Placed a complaint on 31st October 2025 as per their complaints procedure, we are now over 7 months and still no response with a phone system still not working properly. If you want to be robbed blind with as little customer service as possible this company is for you. They take your order, tie you into a contract and then ignore you for the rest of the term and will not release you even though they have failed to deliver under the contract.

Robert Stinton has been excellent helping our hotel even out of hours. Never gives up on any problem and is always happy to help credit to the company.

Thanks Robert for all your help! It was great to get the issues resolved.
