  • 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

  • soozles_ Soozles 🏴󠁧󠁢󠁷󠁬󠁳󠁿💙 (@soozles_) reported from Barry, Wales

    @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?

  • 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 😡

  • 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

    Hey @tescomobile is there something wrong with your network? I’ve had no service for a day and a half now…

  • GarfieldTheCa15 GarfieldTheCat (@GarfieldTheCa15) reported

    @tescomobile I've referred it to the ASA who I'm sure will be in touch with your organisation. In the meantime it's a joke that you cannot yet say what you will be charging in terms of roaming for this summer. I'm a current customer and am holding off renewing *any* of the 4 contracts I have

  • AnnFish21810338 Ann Fisher (@AnnFish21810338) reported

    @tescomobile I’m having massive problems with my phone identifying incoming calls since moving to Tesco and nobody there seems to be able to sort it out. What’s going on?

  • Horne_V Victoria Horne (@Horne_V) reported

    @tescomobile Such appalling service following a number migration issue. No one available to escalate my complaint to. No evidence you are even trying to fix it.

  • ZacharyBirchley Zachary (@ZacharyBirchley) reported

    @TescoMobile I’m disappointed with the service I’ve received. I have been a customer for 2months &my contract hasn’t worked since I purchased it. I’ve contacted customer service many times &have not reached a resolution. I expect better from a major company. #disappointed

  • Lindsay_Brunt Lindsay Brunt (@Lindsay_Brunt) reported

    @paulrdon @tescomobile It’s so bad! But Tesco will blame your phone or area for the issue… just had mine checked at Apple Store and it’s deffo not the phone!

  • jenjynx Jenny (@jenjynx) reported

    @tescomobile hi could you help, my phone signal is not working. Phone restarted, removed sim card and inserted again. Nothing! My sim card is fairly new. Any advice? Thanks Ps: my dad's signal is perfect. He's on tesco mobile too.

  • Lauren_J1601 Lauren (@Lauren_J1601) reported
