    @tescomobile I can’t call or receive calls today, get call fail on them all but I’m able to text and use data without a problem. Is there a problem in the CF63 area?

  • HAndTheElements Hegsy & The Elements (@HAndTheElements) reported from Cardiff, Wales

    @tescomobile what is the escalation process regarding a faulty phone that has been lost by @Tesco? My OAP mother has been without a phone since September and promises to resolve have failed. No senior support from Pengam Green Management or in-store guidance. #disgracefulservice

  • nigelbendybus Nigel Smith (@nigelbendybus) reported from Cardiff, Wales

    Thank you so much @tescomobile for sorting out and reimbursing me for the scam texts I received yesterday. Yet again wonderful customer service from @tescomobile

  • soozles_ Soozles (@soozles_) reported from Barry, Wales

    Seriously getting sick of the awful signal from @tescomobile 4 years I’ve been a customer and have 4 contracts with you spending &150-£160 a month and it’s getting worse everyday! Been trying to speak to someone all day (friend) and constantly getting call failed 😡

    @tescomobile coverage is shocking & appalling- I’m in a town centre you’d expect coverage to be strong. If connected to home wifi that’s fine -if I go out & try to use data & FaceTime - very unreliable/poor connection constantly. I’m paying for a service your not providing!

  • StingRae298 Grumpire (@StingRae298) reported

    @tescomobile Liz, thanks for that Customer Care won't deal with me unless my wife is with me. Now looking at other providers.

  • Kellyclay13 Kelly blue angel (@Kellyclay13) reported

    Can tell my phone is coming to end contract @tescomobile it's going so slow. 😒🙄

  • RichardHofman33 Richard Hofman (@RichardHofman33) reported

    @tescomobile Thank you Maria. But 3 times I was assured via your online chat service from your experts there is no problem to activate the SIM card.Then I don't understand how the Tesco Mobile company is working.I spent money at Tesco on mobile phone with SIM so I expected a bit of service.

  • xxKezzahhxx Kerri (@xxKezzahhxx) reported

    @tescomobile you keep harassing me to pay an overdue bill.The app tells me to go to the website and the website is down. I phone 4488 and it keeps saying the payment can't be processed though the money is sat in my account.. I will not lose my service due to website errors again!

  • miniabbysciuto Deanna Troi 🖖🏻💛 (@miniabbysciuto) reported

    @tescomobile I've done both of these, with no improvement 😔 both my parents phones are on Tesco too: my mum's phone is fine but my dad's has the same issue with no signal.

  • petec_music Pete Carroll Music (@petec_music) reported

    @tescomobile You're chat function on your website does not work. It also doesn't work when processing a top up ! You still own me £15

  • miniabbysciuto Deanna Troi 🖖🏻💛 (@miniabbysciuto) reported

    @humantraffic23 @tescomobile Thanks. Hopefully it's just something like an issue with the local phone mast or something

  • AlibaileyAlison Alison Bailey x (@AlibaileyAlison) reported

    @tescomobile Internet not working

  • millinchip Lea Millinchip (@millinchip) reported
