  • RachelKendall16 Rachel Kendall (@RachelKendall16) reported from Risca, Wales

    @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?

  • 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?

  • 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 😡

  • mind4sportpsych Dr Karen Howells (@mind4sportpsych) reported from Cardiff, Wales

    @tescomobile I have not had a signal for 3 days now. I’ve been told that there is maintenance work being done on a local mast, but even when I move 30 mins away from home then I still don’t have a signal. What is happening??

  • RebeccaBeldam Rebecca Beldam (@RebeccaBeldam) reported

    @tescomobile I did but they said they don’t do loyalty discount anymore which is ridiculous as I’ve been with you for 6 years and you don’t do trade in for old phones either ! Looks like I’ll be looking at another network.

  • RebeccaBeldam Rebecca Beldam (@RebeccaBeldam) reported

    @tescomobile Thanks but they refused to help so I’ll be going to another network.

  • rosheen_hall rosheen hall (@rosheen_hall) reported

    @tescomobile so fed up will little or no service in my area. Over a year now with 1 bar if I'm lucky. O2 say mast is fixed but it's not. Struggling to phone you to complain.

  • weardalepriest Claire McClelland (@weardalepriest) reported

    Come on @tescomobile when is our service in Alston/Nenthead in Cumbria going to be sorted out? No service at all since last Sunday night. No information is forthcoming. It’s really not good enough in such an isolated area.

  • LucyMEDavies Lucy Davies (@LucyMEDavies) reported

    @tescomobile please advise how I contact you as a new/potential customer I have queries regarding setting up a new contract #mobileContract #CustomerService #TescoMobile

  • AlliRondel Alli Cronnelly (@AlliRondel) reported

    @tescomobile @WhichUK it has now been 3 weeks since Tesco mobile have lost my mobile number. How on earth can @WhichUK recommend them?????? Customer Service absolutely rubbish

  • hanna_nadjai Hanna 🦋 (@hanna_nadjai) reported

    When you need to be a Karen because @tescomobile never cancelled a contract you asked them to and won’t give your money back 🫶🏽

  • RebeccaBeldam Rebecca Beldam (@RebeccaBeldam) reported

    @tescomobile I appreciate that but doesn’t help me at this point does it. You won’t offer me any loyalty bonus and your deals are too expensive. Best network I’ve been on but now now.

  • hanna_nadjai Hanna 🦋 (@hanna_nadjai) reported

    @tescomobile @Tesco company customer values and customer service is shocking. -1000/0.
