    @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 😡

    @tescomobile Hi, can you tell me if Tesco intends to support Apple Watches any time soon on a cellular level. If not why? O2 network is used on Tesco mobile…. How far apart can an iPhone be away from a watch if used and will your Apple Watch connect to all available WiFi?

  • 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

  • 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

  • _randa Randa (@_randa) reported

    @tescomobile Well One store said no to 3 handsets being sold then the other store 3 miles away I brought 3 phones on 2 separate transactions with no problem! Fantastic service. My issue is the first store manager was highly rude and intimidating- not good customer care …

  • SGall78 Simon Galloway (@SGall78) reported

    Hi @monzo can you help me plz? @tescomobile attempted to take £15 out of my account this morning even though I'm not with them anymore and they assured me it wouldn't happen. Is there a way to block any future attempts please?

    @tescomobile It's a good job you suggested I call the insurance company, I would never have thought of that myself!! #tescomobileshockingservice

  • sbsam_sam sbsam (@sbsam_sam) reported

    @tescomobile @RABCJ Hi I'm having the same issue. Any idea how to fix ?

  • Charlot21599780 Charlotte Ford (@Charlot21599780) reported

    @tescomobile called 4455 to leave the network because I’ve had nothing but problems to be spoken to like dirt on the floor by one of your workers for wanting to leave, no wonder why I want to leave. disgusting company with the worst customer service.

  • KarenRoss2 Karen Ross (@KarenRoss2) reported

    @tescomobile your service is absolutely tragic! My son was mugged in London on Monday, I reported it straight away. Five days later we still haven't received a New sim and your insurance still haven't processed my claim!
