    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

  • 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?

  • 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 😡

  • 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

    @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?

  • caroljane1 Jane Doyle (@caroljane1) reported

    @tescomobile still waiting for my broken phone to be collected! Pick up slot between 12-1pm.

  • s4bo60 samantha bryson (@s4bo60) reported

    @tescomobile none of your agents are willing to raise my consumer law complaint over the phone, keep going on about warranty which is not the issue as it’s consumer law. iPhone has hardware issues under contract Tesco don’t want to know because warranty is up.

  • neilslater36 Neil Slater (@neilslater36) reported

    @flickhan @tescomobile Same here, was fine but not anymore, if I get a mobile data signal anywhere within a 3 mile radius of my house the speed tops out at just over 1mbps. That's NOT 4g

  • caroljane1 Jane Doyle (@caroljane1) reported

    @tescomobile This number is not working

  • davecarson88 dave carson (@davecarson88) reported

    @Gordon45908442 @tescomobile Gordon, how did you go on as I've had exactly the same problem. Phone lost by DPD, no resolution!

  • Gordon45908442 Gordon (@Gordon45908442) reported

    @tescomobile DPD chat is automated and more unhelpful than you can imagine and I cannot get through to an actual human. I just want my phone delivered so I’m disappointed you’re just washing your hands of it. Good mind to cancel the whole thing and move to @VodafoneUK

  • Dogearedtatty H (@Dogearedtatty) reported

    Why is @Tescomobile mobile data (provided by @O2) so terrible in Exeter? Forget 4G, forget even 3G. It was even failing to get EDGE/GPRS.

  • Gordon45908442 Gordon (@Gordon45908442) reported

    @davecarson88 @tescomobile No help from either Tesco Mobile or DPD. Both tell you to contact the other. It looks like it may be delivered today but we’ll see.

  • JakeHamblin20 Jake Hamblin (@JakeHamblin20) reported

    @tescomobile hi, is your phone line having problems? I am trying to call but the call cuts out about 3 seconds in every time.

  • s4bo60 samantha bryson (@s4bo60) reported

    @tescomobile I have tried to raise a complaint twice now and no one seems to want to raise it. Or contact me regarding the actual complaint
