    @tescomobile worst customer service I have ever experienced! Faulty phone only replaced with a grade A replacement after being sent for repair 3 times (not a new phone, yet still under warranty) the replacement we received doesn't work neither 😡 shocking experience

  • DogsBeTheBest Magic_Staffy & Webber (@DogsBeTheBest) reported

    @tescomobile I'm not receiving calls and texts but can send them. Is there a problem locally? I am at LL11 4TQ

  • joystur Joystir (@joystur) reported

    @tescomobile I've just arrived in Canada and my phone won't work because I've exceeded my cap set at £40 but I only made one call of a minute's duration when I arrived. I can't login to my account either to see what's happened. I need to be able to use my phone. Please help.

    @tescomobile I’m finding that when I have Wi-Fi turned on but not connected when I’m out my mobile data won’t work, so I have to switch to airplane mode for 10 secs to ‘reset’ it. Only happening since I switched to you guys, any idea on a long term fix?

  • dushiqi Robert Dubsky (@dushiqi) reported

    @tescomobile Tescomobile app does not give number for voicemail. Google says 171 but number not recognised. As a new user, I need help!!!!!

  • DogsBeTheBest Magic_Staffy & Webber (@DogsBeTheBest) reported

    @tescomobile No, I've tried from 2 different numbers and not received anything. But they can receive my messages. Fingers crossed they fix the mast soon then

  • sumitsolanky9 Sumit (@sumitsolanky9) reported

    @Tesco @tescomobile … This is what made me just have to laugh at your company… I was trying to get a customer service number and the number that is on the website 0800505555 is only 10 digits… I’ve just had enough with your company now 😤🤬

  • DebbieSelf18 Deb (@DebbieSelf18) reported

  • GalaxyWorksh0p Dan R (@GalaxyWorksh0p) reported

    @tescomobile Haven't been able to get any signal for the last 2-3 hours, normally it's fine where I am (Truro, Cornwall) - is there an issue in my area, or just something up with my phone? Thanks!
