    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 😡

  • 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

  • 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?

  • 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

  • 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?

  • steviewatson01 Steve Watson (@steviewatson01) reported

    @tescomobile a week on and porting issue still hasn't been sorted. Can someone in the porting department please message me and sort this out. I've done everything, new SIM card etc. Nothing has worked. I can't receive calls or texts apart from other Tesco mobile numbers.

  • HofKnocker Adrian Tompkins (@HofKnocker) reported

    @tescomobile hi you told me yesterday that there was nothing more you could do regards my complaint. I will give you one final chance to resolve this matter satisfactorily within 14 days or to send me a letter of deadlock.

  • cymraesydwi Cymraesydwi 🏴󠁧󠁢󠁷󠁬󠁳󠁿 🇺🇦 💜🤍💚 (@cymraesydwi) reported

    @robyn_goch @O2 @tescomobile Honestly the complete lack of customer service has really shocked me. They've offered me a month's free line rental.... On a phone I can't use you mean!? Helpful!! Dire, dire service with no end in sight!

  • davecarson88 dave carson (@davecarson88) reported

    @Gordon45908442 @tescomobile Every time I manage to get in touch I'm told the issue is being escalated and investigated. Now the Customer Care number is not working

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile no data roaming in Germany for 2nd time on second trip in 2 week, your telephone support have given false assurances multiple times but still no data roaming, very poor service and no reasonable explanation given.

  • kelda_kelly Dr Kelly Henderson (@kelda_kelly) reported

    @tescomobile Thanks I have already registered. It’s been a couple of days so was hoping for a general indication of when service being restored - hopefully it’s soon.

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile I have no problem with roaming in UK so I don’t see how this can be hardware ?

  • 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.

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile I have tried all networks same issue

  • The1JDavison John Davison (@The1JDavison) reported

    @tescomobile Only have E signal (2G) so no error just no 3G and above
