  • 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?

  • 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 😡

  • 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?

  • 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

    @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 are you having any signal problems that you know of? I’m waiting for an important call and have no service, so they can’t even leave a voicemail #tescomobile

  • trina1982t Trina1982t (@trina1982t) reported

    @talkSPORT @Sjopinion10 @tescomobile I can't understand the complaints about having to go to the 'smaller' teams in Europe. You never know if you're going to watch a 5-0 thumping or a 1-0 giant killing.

  • lesherring3 les herring (@lesherring3) reported

    @talkSPORT @Sjopinion10 @tescomobile Just a pity the six are carrying such large losses. Maybe if football was back to being run as a business for the fans this sort of **** would not happen.

  • MiserableFatMan David (@MiserableFatMan) reported

    @tescomobile having a bit of trouble with your app, just keeps saying “oops, something went wrong. Please try again “

  • LukeSuddens Luke Suddens (@LukeSuddens) reported

    @tescomobile 305 working days? I do hope it does take that long! 5 days is tomorrow. If it isn't here tomorrow, I'll be back on for support and escalation.

  • MaxP37 Max Power (@MaxP37) reported

    @tescomobile It has nothing to do with your coverage! It used to work well. Since around Feb we have all been having issues. Either O2 or yourselves are doing something to affect service, maybe throttling back. If this continues we will just leave, contracts are up in May.

  • Lalyo79 Kam (@Lalyo79) reported

    @tescomobile @BBCWatchdog Absolutely disgusted by the lack of help from Tesco Mobile. Unwilling to help. Paying for a service which I’m not getting #tescomobile #Disgraceful #whodoicomplainto

  • jrogersbstreet J Rogers (@jrogersbstreet) reported

    @tescomobile It has always been the case. You’ve had a few complaints off me. Basically your waving the white flag here in SWales. Your engineers know this so you really could sort the pricing out. I shouldn’t be paying the same as someone getting full signal.

  • SteveAttw00d Steve Attwood (@SteveAttw00d) reported

    @tescomobile Reporting a poor mobile signal issues takes me on the the 02 net work. 02 then contact me to say they are unable to resolve or escalate the issue because I'm a Tesco mobile customer.

  • ACCMummy Sally Collett (@ACCMummy) reported

    @tescomobile I cannot be without a phone, and the insurance i took out, which would have provided me with a replacement phone, cannot be used as, rightly so, they are saying it is a warranty issue.
