Zusi Limited Reviews 

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.

I set up a new phone contract with Zusi just recently,
but the network didn't seem to have good coverage in my area. Zusi then set me up with a network which is now working well for me.
David was helpful and courteous and guided me through the process in a friendly manner. Many thanks!

Great service throughout until you go to leave.
Shame as would have gone back for a quote at renewal but not after the struggle to transfer. Were told that the handsets would not be required back and all of a sudden, contracts quoted and handsets required back or payment in lieu. Shame they don't all tell you the same things

David and Chris , have been Proffessional , consistent and patient in dealing with my VoIP phone and mobile phone contracts .
Customer service has been superb , I lost my Sim without it no I was snookered so they swiftly replaced the next day and made sure I was back up and running . I really couldn’t have hoped for better .

I do look forward to dealing with them more as my business grows and really like that they are a local Company very approachable for a technophobe like me .

Much appreciated chaps carry on the good work :)

this is a long story but i will try to keep it brief , we have been with Zusi for 4 and a half years after the 3rd year we was asked to take out a further 3 years at the same price supplying 2 new phone and a new hub
let me tell you , the new phones arrived with no power adaptors no dongles and no new hub , i have had to carry on using the old phones until 1 week ago but carry on paying for the new phones but not only that the bill has gone through the roof from the agreed £83-00 per month to £180-00 + we tried and tried to get the missing parts supplied , i think some adaptors arrived a couple of months ago but no dongles or hub
i have now moved to a new supplier For £93-00 per month with all new equipment , when changing over we have to port the numbers of which the new supplier requested from Zusi and they even held this up by refusing to port the numbers demanding we pay over £2300-00 in settlement this is illegal so we got offcom to get involved and the problem was soon solved , i think it's zusi who owe us to be honest
i don't usually write reviews , but this has been the most horrendous experience
so please take my advise steer clear you have beeen warned

Abby at Zusi is always extremely accommodating and a pleasure to deal with in general!

I am a new starter, and have been having issues with my company phone.

The support and quick response over the last week from Abby has been 10/10!

She tried to come up with every scenario that could be wrong with the phone and went above and beyond.

Chris booth from Zusi made transferring our contracts effortless. I will definitely be giving Zusi an opportunity on my other energy and phone contracts. Absolutely great service thanks

I cannot praise the professionalism of Sean Wright enough. We are in the process of upgrading our mobile phones and landlines. 10/10 for patience in answering every question in an efficient and speedy manner.
I would recommend Zusi to any business and look forward to future business with Zusi.
Well Done!!!

Having recently come out of contract with both our mobile phones and electricity suppliers, I cannot praise the services of Zusi enough, especially Chris Booth and David Mcauley. Our switch to new providers has been professional and smooth throughout. Would highly recommend.

Having switched our Parish phones from our previous provider to Zusi in July, the cost to Parishioners is now a THIRD of the cost of our previous provider. Even better, we've been plagued by O2 for months, but Abby from Zusi Customer Service has fought tirelessly on our behalf, taken away all my stress, and sorted it all out. Thank you, Abby! This company is highly recommended.

Great service, prompt and efficient, they know what they are doing! I can sit back and trust them to take care of it..

Thanks for making this easy!

Will definitely recommend

This company, in particular Vikki in their sales team has chosen to deliberately SPAM our company over the last four weeks sending completely unsolicited emails. These emails are personally addressed and make us feel pressured to reply, although we have never heard of this company, we actually feel violated, that they have compromised our data security.

They insist on sending us overly familiar emails referring to the content from the previous completely unsolicited email!

Calling their office just now, "Vikki" doesn't even work there, someone called Lee is now holding her direct mobile number. Lee said that he gained our information from a marketing campaign, I do not believe that this is/was the case. The fact that we are being emailed from someone who no longer works there, and has not for a while, tells me that they are nothing but spamming bast@rds!!!

In my opinion, this is definitely a company to avoid if there method of promotion in 2023 is SPAM!

Fabulous service in our new lines for the shop. Chris made it all simple and clear. Many thanks
