    @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

    Trying to leave @tescomobile and unlock a phone to a different network should honestly be a Crystal Maze challenge. JUST TELL ME WHERE TO PUT THE PUK CODE YOU COWARDS

  • LilacNannie LilacNannie (@LilacNannie) reported

    @tescomobile Don’t go out. Wipe didn’t help.

  • Jess_Simpson645 Jessica Simpson 🇬🇧🇬🇧🇬🇧 (@Jess_Simpson645) reported

    @tescomobile Yes I am with you, I think you use the O2 network? They are always O20 numbers - if only there was a way to block that area code. I have had 10 calls this morning and don't want to have to spend my life reporting each individual number. Maybe a number change is my best bet.

  • hoodedpigwoman hoodedpigwoman (@hoodedpigwoman) reported

    @tescomobile 2nd call to option 4 was a girl, she was helpful but her system only accepted mobile numbers: my mobile isn't working! Then I got cut off. Then spoke to man who checked code had been requested. It had. Nobody could offer a solution to me having no calls or data for 7 days tho!

  • DeniseM30781820 Dee Martin (@DeniseM30781820) reported

    @tescomobile So apparently I dont meet the criteria for a Tesco mobile phone contract 🤔 and yet I have a Tesco Credit Card, an excellent credit score, no Cifas markers, no outstanding debts, no CCJs and yet still I've been turned down for credit 😤

  • ccbespokeart Char Callin (@ccbespokeart) reported

    @tescomobile @Tesco can someone get in touch with me ASAP or tell me who to contact to change my email account attached to my phone number and my club card as my email was hacked. Thank you for your help. #cyberfraud #onlinefraud RT

  • LilacNannie LilacNannie (@LilacNannie) reported

    @O2 And that’s why no one should get a #Tescomobile on #o2 network - you don’t take responsibility for your failure. Take note people...

  • LilacNannie LilacNannie (@LilacNannie) reported

    @tescomobile I enter it constantly and you repeatedly tell me there isn’t a problem!

  • tlc41 tracey-louise (@tlc41) reported

    @tiredgruffalo @tescomobile Ive had nothing but problems for days mobile data working when it feels like it

  • Jess_Simpson645 Jessica Simpson 🇬🇧🇬🇧🇬🇧 (@Jess_Simpson645) reported

    @tescomobile @O2 not sure which of you might be able to help me but I'm being absolutely bombarded with unwanted spam calls from O20 numbers. As quick as I block them they pop up again with a different number. Latest one 020 3768 9411
