    @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

    @tescomobile Received a new SIM. No data available. Just spoken to lovely CS agent who says there’s an ‘unknown issue’ with data for customers who have made recent changes to their account. Please advise when this will be fixed & compensation details.

  • manutdTOPFAN73 Joneschris (@manutdTOPFAN73) reported

  • preemiemummy18 Becky (@preemiemummy18) reported

    Fast forward to this morning. I realised what was wrong and called our doctors. I got an apt but they said someone would need to see him. I rung #111 who to be fair had a nurse ringing back really quickly. BUT apparently there was a problem with @o2 and @tescomobile use o2 masts.

  • Lisagoodey Lisa Goodey (@Lisagoodey) reported

    @tescomobile @WhichUK Not for me, had 20 years no problems with o2, been with Tesco Mob since Fri, no data connection since then. Apparently it’s a known issue since May, nobody told me this when i signed for 2 contacts. Calls to the helpline are useless, they have no idea if or when it will be fixed

  • gez_666 gez howarth (@gez_666) reported

    @tescomobile @giffgaff They said every time they tried to put my details through it came up with a technical error, they reported it and apparently it was a known issue

  • MoonEnvoy ChilliDan (D.Munoz) (@MoonEnvoy) reported

    @tescomobile Been with you but unfortunately, even though I'm due for an upgrade, I can't because I changed my address. How do I proceed to cancel my account with you?

  • DawnLou_S Louise0901 (@DawnLou_S) reported

    @tescomobile @WhichUK @tescomobile I logged a complaint 2 weeks ago and still have not had a call to resolve. Numerous calls have been made to your customer service department promises of calls to be returned which have never been fulfilled. I am absolutely shocked of the delivery of your service!

  • TelfordLes Les Capon-Telford (@TelfordLes) reported

    @tescomobile No they have not shocking service. I will not recommend Tesco to anyone and am contemplating a return to o2 even though they are more

  • TelfordLes Les Capon-Telford (@TelfordLes) reported

    @tescomobile OMG what a shambolic new customer experience. We stupidly entrusted you to transfer 4 numbers and spent hours on the phone giving pac codes. Turns out you had not done your part. Only found out when we called to find out about delay. Anyone transferring be warned.

    @tescomobile @Tesco Hi, yes I have checked my account but I never seem to get the points on my card.
