  • 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

  • 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?

  • _Gingernut_ Daren (@_Gingernut_) reported from Bridgend, Wales

    @tescomobile I’ve had no signal for the last 3 days, your unhelpful app is useless. What’s going on?

  • 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?

  • 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??

  • 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

    @tescomobile hi Tesco. We have an account with four phones in our family in Banbury. The reception for calls and data over the last week has been terrible. Any news? The coverage said there was an issue with a mast has this been resolved?

  • Mollym00z Mol (@Mollym00z) reported

    @tescomobile is the a network outage in parts of London, namely Harrow? I have one of your chat team fobbing me off! I am unable to dial out from my mobile.

  • _nathanGAmartin Nathan Martin (@_nathanGAmartin) reported

    @DPDgroup_news @DPDCare @tescomobile I am beyond frustrated with this ridiculous courier company and would like a resolution on this ASAP. I have even suggested personally collecting it for the depot to be ignored again.

  • Vix_D Vickii Devonald (@Vix_D) reported

    @tescomobile Absolutely despicable way to treat a grieving family, cutting their family package off and insisting you can only speak with the deceased account holder 😡 #DoBetter

  • DL_BSL Drew Ledson (@DL_BSL) reported

    @tescomobile Since upgrading my contract I cannot access my data. Once my Safety Buffer has been used I am cut off. Two days onto customer service and an afternoon in store. No joy. Will you cancel this contract as you can't fulfill it?
