    @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?

  • 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 😡

  • 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?

  • 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

  • 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

  • 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??

  • Robert_May_ Robert May (@Robert_May_) reported

    @tescomobile this super helpful network suggest I call @DC_Police to resolve a minor matter for one of their customers. Instead of being super helpful I should report the old lady to plod for causing a nuisance. No right-thinking person thinks that is helpful.

  • AndrewBlewett3 Andrew Blewett (@AndrewBlewett3) reported

    @tescomobile Tesco mobile took almost £1000 in payment from a broken & out of use phone - an account they knew was dormant. Offered a token mini-refund with two week limit. Terrible service. Never again.

  • wildlifelover0 Wildlife mad (@wildlifelover0) reported

    @tescomobile @O2 Yeah like I keep saying POOR. Yet you were happy to keep taking my money. Sounds like fraud.

  • GoldenScarf2021 Golden (@GoldenScarf2021) reported

    @KirstyHawkins9 @tescomobile Wow! Is this for real?! I’ve never been that lucky with my subs🙄

  • I_Returneth Stephen(insert appropriate virtue signalling flag) (@I_Returneth) reported

    @tescomobile But if that comes out of your phone: you got issues.

  • TuxedoMaverick TuxedoMaverick (@TuxedoMaverick) reported

    @talkSPORT @tescomobile Unfortunately Kane’s brother has **** the bed here. He’s missed his chance and has been grossly mis advised by people around him who’s motive was making money off him.

  • Stevieboi696969 Steve (@Stevieboi696969) reported

    @Nichola31062334 @talkSPORT @tescomobile Tottenham and chelsea don’t do business. Ever and It would be £200m plus lukaku. £150m for Kane and £50m to take that bag of ****

  • PissedOffTory RealTory (@PissedOffTory) reported

    @tescomobile No, Tesco Mobile is super unhelpful. I can't top up my MiL's mobile online without having the phone receive a text code - this won't work because A. she lives 200 miles away and B. she gets a crap signal at her house. I don't have this problem with my wife's EE phone ...

  • andyjmcgowan Andy J McGowan (@andyjmcgowan) reported

    @tescomobile So why are you pushing for people in this area to take your miserable service. I was with Tesco mobile at my old address and it worked well, but not here.

  • Robert_May_ Robert May (@Robert_May_) reported

    @tescomobile have an elderly customer who has put my landline into their mobile phone, their escalated "customer care"suggestion to resolve the continuing nuisance is to call @DC_Police and get them to provide help to a @tescomobile customer Unhelpfully hiding behind GDPR
