    @tescomobile Moved from EE to Tesco mobile for one of these deals. The difference in customer service is shocking. All I’m trying to do is transfer my number - 9 phone calls, a different response each time and now day 2 of no working phone number. Truly, truly awful.

  • mikegrichards Mike Richards (@mikegrichards) reported

    @tescomobile Hi just joined you after leaving 3. You have retained my number but when you send one time code to sign in it goes to original number for new SIM not my number you have ported over.

  • amie_lavinia AmieLavinia🌹 (@amie_lavinia) reported

    @tescomobile Hey, I'm on a sim monthly contract, but I want to cancel it as I just dont get much usage from it anymore. If I cancel, will my sim change to pay as you go & I get to keep my number? Or will I need to get a new sim? Unsure how it works 😕

    @tescomobile Hopeless, ignorant and arrogant.Useless service from every department. That is my summary of Tesco mobile, I will stick to O2 and Vodafone.

  • RubyTinkerbell RubyTinkerbell (@RubyTinkerbell) reported

    @tescomobile Yes it's over the 14 days; it's mainly at home. There's just no signal at all, so I'm unable to do anything! I shouldn't have to pay any cancellation charges if you're not providing the service I'm paying you for!

    @tescomobile @ipujilitz Same - can’t log in on website or use app. Tried clearing cookies etc and still not working.

  • mikegrichards Mike Richards (@mikegrichards) reported

    @tescomobile Hi. Old providers SIM card does show no service so followed instructions given. Will try again later. Thanks.

    @tescomobile It said there were no issues, not helpful... there WERE issues, and they were spread out geographically.

  • Sharond_01 Sharon Donnelly (@Sharond_01) reported

    @tescomobile Surely the fact that we’d transferred away from the network means payments stop. I’ve not had to sort that out with other networks before.

  • Phoenixx89x Robbie (@Phoenixx89x) reported

    Been a loyal @tescomobile customer for many years now and I’m being told that the options for my faulty phone are wait and see if a new one is in stock or cancel my contract? They also don’t phone customers back from the exchange department because A NEW CUSTOMER takes 1/3
