    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

  • 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

    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??

  • 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?

  • 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

  • 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?

    @tescomobile trying to buy a phone on your site and the basket just will not load. Is there an issue or can you not buy from you just now? Thanks

  • theseguins theseguins (@theseguins) reported

    Hey @tescomobile, I was enquiring about how to move provider, told them I was going to move next week but your guy has just cancelled my subscription - right before the chat closed. Now I have no mobile service and can't contact anyone. REALLY bad service!

  • Jasehendy Jason G Henderson (@Jasehendy) reported from Wadebridge, England

    @tescomobile issue with false data readings unresolved despite Tesco CC request to investigate the problem. It's been about 8 days without an answer & longer since the issue raised. I think it's time to leave TM.

  • Amanda_Pebbles Amanda Finestone (@Amanda_Pebbles) reported

    @tescomobile really? Three lengthy phone calls, one agreement now reneged and you want me to pay £97.50? No wonder retailers are going under. Terrible customer service, bordering on criminal. Appalling

  • Gumdrops33 Gail (@Gumdrops33) reported

    @VodafoneIreland After 2 weeks of no home broadband, one engineer that didnt turn up and two @tescomobile at their data limit due to hot spotting (WFH) STILL no sign of anyone to fix it. HELP PLEASE 😭😭😭

  • interestedgirl2 interested girl (@interestedgirl2) reported

    @tescomobile. Not impressed at your service after being a loyal customer for years- will be researching SIM contracts with other companies

  • HellcatHellenic Hellenic hellcat (@HellcatHellenic) reported

    Is that acceptable @tescomobile @Tesco ? I was told the fraud team would come back in 5-7 days. Been way over that. Then fobbed off by a manager who refused to speak or help out the advisor on the phone to me. You lot are an absolute shambles

  • chipmunkowl Kim Noadster (@chipmunkowl) reported

    What a nightmare @tescomobile placed an order last Tuesday, was lost by DPD. Horray finally got to the bottom of it yesterday, replacement sent. Arrived today but no SIM card! Tried to call, systems down. Online chat, replacement SIM now being sent... all in all a real pain!

  • ReaddyHeather Heather Readdy (@ReaddyHeather) reported

    @tescomobile your customer service is horrendous!! What we need to do is to be able too pay of the safety buffer in order to be able to use the phone again!! Why has it taken 3 hours to get no where! 15 years of loyalty has amounted too nothing! We Can't wait too leave!

  • CammieRacing TFz Cammie Racing (@CammieRacing) reported

    @Ofcom @tlaindon1 @tescomobile If it all comes under one contract, and it does say 36months... otherwise soon it'll be broken up to handset/airtime/warranty/accessories/data seperately for 60months.
