  • 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

  • TRHComposer Thomas Richard (@TRHComposer) reported from Cardiff, Wales

    @tescomobile my mobile data has just stopped working. Still got over 10GB available to me though. Is there a Network problem?

  • 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?

  • Saeed_Ahmed02 Saeed Ahmed (@Saeed_Ahmed02) reported from Victoria, Wales

    @tescomobile needs to better support the Google Messages app. I quite like using the Google Assistant to send texts and it always comes back saying 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

  • 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 😡

  • _housematerants The feeling when you live with idiots (@_housematerants) reported

    @tescomobile Yeah this is all meaning well and that but since you don't actually run an actual network, you piggy back off o2 you don't need to put the prices up because you aren't investing in the network.

  • WinstonHill17 Winston Hill (@WinstonHill17) reported

    @tescomobile @ThreeUK are terrible. I’ll be looking at Tesco ( unless @AldiUK start doing mobile and they’ll be even cheaper and better).

  • mudlarklives Clay Harris 🇪🇺 (@mudlarklives) reported

    @schnuckster @mvonschantz I had a similar thought, as a @tescomobile customer on O2's dreadful network. Although the gradual disappearances of corded landlines might be more relevant.

  • NoVinylLynal novinyllynal (@NoVinylLynal) reported

    @tescomobile You don’t use your own network. You piggy back of others that have invested in the strength of its service.

  • David76866940 Dr Zeus (@David76866940) reported

    @tescomobile Oh really! I'll be honest with you, it doesn't sound that way to me. I work in telecoms but not affiliated with any network but when I heard the advert, I was a little surprised and had to ask the question.

  • saintdavid2911 david powell (@saintdavid2911) reported

    @tescomobile hi. My wifes phone on my account has. Beenn charged for 3 premium rate txt messages of £10 each all at the same minute on 19th March... help!!

  • Alphawolfy_ Matt (@Alphawolfy_) reported

    @tescomobile Just got a letter from @O2 hiking my tariffs up a few days ago for no valid reason, just because they can so long as they tack a flimsy excuse onto it.. It's a disgrace, you are right. They treat anyone who's already a customer like garbage because they already 'have' us. :/

  • BennettArron Bennett Arron (@BennettArron) reported

    @tescomobile Over an hour. Twice. And it's very, very important. Shocking service.

  • BennettArron Bennett Arron (@BennettArron) reported

    @tescomobile As I have now been on hold for your Additional Support Team for an hour, and your Chat function doesn't work on your website, can you tell me how I can explain to my father, who has dementia, that the phone company he uses has no interest in trying to help? Thanks.

  • CRy3Gen CRy3Gen (@CRy3Gen) reported

    @tescomobile Yeah you could not stop charging me when I got scammed. 3 times I asked you to stop charging and 3 times you carried on charging me. CONCLUSION , never buy into a contract . #giffgaff
