    @tescomobile I don't honestly think it is... I think you have a problem with your own phones and staff training. Many times, they have had the phone on mute, and then found how to come back, and unmute the phone. I could be wrong... but it has mostly seem a fault on your own end!?

    @Welshmam3 @tescomobile Yep. Seems to be there are issues with both lines now. I want a PAC code for both and am cancelling. I've had horrendous service from them.

    @HParf @philburns @tescomobile I'm leaving as soon as I can. I've never had such appalling service. Beyond disappointed. The man in store was mortified at how poorly I'd been treated... And no end in sight! Thanks xx

    Appalling customer service from @tescomobile waiting 25 days and counting instead of 24 hours to transfer my old mobile number! No resolution no ownership no timeline ….. nothing. Would not recommend Tesco mobile to anyone. All I want for Christmas is my old number back!!

  • Leahambrose2 Leah ambrose (@Leahambrose2) reported

    @leahtarnya @tescomobile I know I wish I never did I’m sure o2 wouldn’t treat me like this - never again! Please avoid tescomobile

  • cunliffe_gail Gail C (@cunliffe_gail) reported

    Anyone having issues with @tescomobile voicemail? I've been migrated to their new system & now the phone only rings about 10 seconds before going to voicemail. Used to be able to change how many sec's before voicemail but not on new system. Why change system if it's not as good?

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

    @MgraNLea @tescomobile Thanks. I'll definitely be doing this. I just spent an hour and 45 mins in store trying to resolve this. Still no resolution. I've got a temp number now and my son is being sent a new SIM. I am absolutely gobsmacked at how awful the service is with Tesco

  • NicNacG1979 Nic (@NicNacG1979) reported

    @tescomobile in November ordered a pay monthly contract for my daughters Christmas present paid £180.00 up front for the device and the first monthly payment. Direct debit setup. Christmas Day can’t get anywhere with the sim contact customer services contracts cancelled??!!

  • kerrison999 Chucky (@kerrison999) reported

    @tescomobile Joined tesco mobile and they said my old number would be ported on 5 December. It’s now the 24 December and it still hasn’t happened. My old number was cut off 2 weeks ago! Getting nowhere with their customer service and not happy!!!!

  • APhillips1962 Andy Phillips (@APhillips1962) reported
