TESCO Mobile has seen met with a number of complaints in recent days, with a number of users taking issue with its customer service.

Users have taken to Trustpilot to complain about the service, with one user labelling them "abysmal".

A second person, Adam Kupiec said they were left frustrated at the “disrespectful customer service”.

They said: “I am already a customer. I tried to order another phone but unfortunately it didn’t go through.

“I phoned customer service then. Absolutely arrogant customer service representative man asked me when I applied for so many contracts.

“He raised his tone multiple times. I said it was probably by mistake and he said no because you don’t have money in your bank. He was disrespectful and extremely arrogant.”

The customer added they would “never order” with Tesco Mobile again with the company replying and apologising to ask the customer to pass the details on so it could be fed back.

Another user, meanwhile, Adam Moseley, said they had been having issues with their Sim card and that they had contacted Tesco “multiple times” through an online chat function, but that they “keep being told to ‘allow 24 hours’ and they won’t give any more detail or an accurate time scale”.

“Very frustrating and I don’t know if/when it will be resolved.”

Another user added that the company “kept sending letters to my late wife asking for payment of an outstanding balance even though I had previously contacted them and they agreed nothing was payable”.

“When I complain they agree nothing is payable but are not able to confirm in writing and have said to ignore any further letters that may be sent.”

Somebody else added that the service was “ridiculously overpriced” while one user reported an issue with a charity sim.

They explained: “Was given a free Sim for six months from the Trussell Trust, however had to beg for its renewal every month via their chat service. Alas, it was an utter waste of time.”

The complaints come a month after money saving expert Martin Lewis responded to a tweet from a fan who had asked: “Please tell me why Tesco Mobile don’t have to replace a mobile handset which is faulty and within 30 days of purchase?

“Assistant opened phone and sim clip snapped off so they say damage not covered by their guarantee.”

Lewis replied: “Your rights are with whomever sold you the mobile. If that was @TescoMobile, which I assume it is, then their guarantee is irrelevant.

“You have statutory rights to have a replacement of faulty goods within first 30 days. Tesco should know this, I hope they will respond to your tweet.”

In response to The National's request for comment, Tesco said "complaint volumes have reduced month on month, including negative reviews made on Trustpilot, and in the 2024 Which? survey, Tesco Mobile received the highest customer score of 83 per cent".

It also said it is the only mobile operator in the top 10 of the 2024 UK Customer Satisfaction Index.
