  • 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

    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??

  • 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?

  • 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

    @tescomobile hi, is your webchat not working today…?

  • samvj88 Samantha Joy (@samvj88) reported

    @tescomobile Hi, hope you can help. Daughter is in Mexico & unable to make calls. I’ve updated her safety buffer but she has a message to say she only has £1 left, her account says £50, can you help?

  • truebluey69 Kevin Thompson (@truebluey69) reported

    @tescomobile I am very disappointed that Tesco has decided to go along with the other money grabbing mobile airtime providers. . except O2.. which puzzles me as you use their mobile network... profiteering ?? Anyway, tesco will be losing 6 contracts before the end of the year.

  • Pig_Maiden Kerry Canning (@Pig_Maiden) reported

    @tescomobile Still having problems, Rob. After 9 phone calls & a surprising twist where I couldn't even call or text yesterday, I now have to wait for SIM no. 3 to be delivered...some time after Wednesday. I've been told several times everything would be reset & it has never happened. Awful.

  • seymourjames3 Jimbooooo (@seymourjames3) reported

    @tescomobile @Pig_Maiden Sean I don't know about @Pig_Maiden but my issue was with restrictions that tesco put on automaticaly to sim card but there is nothing u can do about it for me tesco did not tell me and i have gone round in circles so I will be leaving no help whatsoever

  • therealasliatta qari saab (@therealasliatta) reported

    @tescomobile fix up

  • wstephw Steph Thomas (@wstephw) reported

    @tescomobile Thanks for responding. I very much hope you will issue my sons refund now and not fob me off like the rest of the customer service team.

  • m0untain_ash jehan p(ro)uvaire (@m0untain_ash) reported

    @tescomobile Just did, have spent about an hour on the phone with customer care and was told to go into the shop which I can't do atm

  • SmileyMatthew91 Matthew Hall (@SmileyMatthew91) reported

    @tescomobile No problem, I’ve private message @tescomobile with the details

  • Pig_Maiden Kerry Canning (@Pig_Maiden) reported

    @seymourjames3 @tescomobile Thanks, Jim. Utterly useless shower of charlatans. Happy to take the money but no regard for customers. I've documented everything. If not resolved soon I'll be bypassing Tesco altogether and taking my issue to the relevant ombudsman. So many folk having similar issues. So poor.
