    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 😡

    @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?

  • 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?

  • 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

    V poor service @tescomobile tried 5 times to top up, then 18 minutes wait to speak to customer service who didn't help and told me to try again, with no jo@

  • jammydevil Angela JP (@jammydevil) reported

    @tescomobile trying to call and am warned by your voicemail system that I’d be better off using webchat. Tried that - not working either. Twitter is my last resort. Please DM me

  • KeithRadcliffe Keith Radcliffe (@KeithRadcliffe) reported

    @tescomobile Really? You let a buggy website go live then can't fix it. Unbelievable.

  • STaylorFranklin Sue Taylor-Franklin (@STaylorFranklin) reported

    @tescomobile hi I ordered my fone yesterday for delivery today but have had no notification ema/text or anything! Help!

  • Mark29071823 Mark (@Mark29071823) reported

    @tescomobile Well I’ve been told they are experiencing major problems but online the service status still says excellent so new people will join under false information. Like I did 18 months ago

  • ianstobbart1 ian stobbart (@ianstobbart1) reported

    @tescomobile good evening Why can I not send MM pictures and I have no issues with text messages

  • RichardHofman33 Richard Hofman (@RichardHofman33) reported

    @tescomobile Hi Maria. I tried the link on all 3 main browsers so I don't think pop up might be the problem. But anyway, what about should I chat with the staff there again? I chatted with them 3 times already and they were very helpful and always assured me the SIM card will be activated🌞.

  • Mark29071823 Mark (@Mark29071823) reported

    @tescomobile The best bit of the service checkers says use hotspots or your home broadband lol but we will still charge you every month for a service you are not getting basically stealing money every month

  • gerimac74 Gerimac74 (@gerimac74) reported

    @tescomobile I phoned customer services as i got nowhere in store even though I got the phone as a replacement handset via my insurance it didn't come with instructions etc

  • claireloopylou Claire Louise (@claireloopylou) reported
