    @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

  • 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?

  • 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?

    @tescomobile Want to leave your terrible network!

  • AinsleyAllister Ainsley Allister (@AinsleyAllister) reported

    @tescomobile I am again complaining about a problem all your customers living in the SA3 are having with your O2 network mask ! Our mobile calls are cutting out with each call for about 10 secs and this has been an ongoing problem since December! O2 are aware of this!

  • Stuntgoat75 Stuntgoat Animation (@Stuntgoat75) reported

    @tescomobile No signal since Monday, given lies that it's antennas, server changes, when one of you call centre people knackered it whilst I was on the phone to them, but no one wants to admit it, so am just fobbed off.

  • Ducky09 Stephen John (@Ducky09) reported

    @tescomobile is the tesco mobile app having issues? Mine won't load.

  • ilzvmanny Leaked🤙🏽 (@ilzvmanny) reported

    @tescomobile been nearly 2 days and absolutely no service in Blackpool, your engineers are still fixing it apparently, when can I ask?

  • Stuntgoat75 Stuntgoat Animation (@Stuntgoat75) reported

    @tescomobile any chance of you actually fixing my network connection, rather than just giving me a load of lies.

  • deadstar37 Vicky 💙 (@deadstar37) reported

    @tescomobile hi my mums phone has no dial tone when she rings me. Every other number on all networks she does but not mine. EE says the fault is with her provider (you) can you help? She’s got a very basic phone alcatel one touch

  • Stuntgoat75 Stuntgoat Animation (@Stuntgoat75) reported

    @tescomobile Well phone still isn't working and messenger isn't replying so yep same old **** 👍

  • realmwelljag Raymond Rose (@realmwelljag) reported

    @tescomobile I have done so. It's a shocking way to treat a customer and no reward for long term loyalty

  • Matt__Pomroy Matt Pomroy (@Matt__Pomroy) reported

    @tescomobile Congratulations! But sadly you advertise in The Daily Mail so I’ll never use your service. Please stop and then we can be friends again. #StopFundingHate
