    @tescomobile I already know you can't help me, unfortunately. If you could direct me to a manager though who is willing to explain exactly what the problem is and why it can't be fixed, I would be very welcome.

  • DiptiSh95223972 Dee Sha (@DiptiSh95223972) reported

    @tescomobile Do you just train your staff to cut calls when they cant deal with peoples enquiries? 22 calls later my issue hasnt even fully been heard. Been trying to resolve since 23/12/2022! If you ask for a manager none are ever available! I will be exercising my rights 2 canx

    @APhillips1962 @tescomobile My poor dad is 77 years old with no communication to family and friends, whilst Tesco keep fobbing us off, they’ve asked me for the sim card number untold times and they still haven’t managed to resolve the issue and now im being asked for it again.🙈
