    @tescomobile I can’t call or receive calls today, get call fail on them all but I’m able to text and use data without a problem. Is there a problem in the CF63 area?

    @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

    @Jennife14435458 @tescomobile Oh the old grey stuff works sometimes Jenn, just sometimes Plus 'procedures' noted 'over the shoulder' of 'genius' hubby help sometimes too It's a cobble, reverting back to known 4G connection but it's working, for now.

  • berta_pxx roberta paterson (@berta_pxx) reported

    @tescomobile I would understand this if I was on a much more reduced plan then it would be more of use to us but we get enough mins and texts and Unlimited Data!! therefore it is absolutely useless to us we don't gain anything at all. Other networks can easily fix this why can't tesco??

  • w4ndle Ian (@w4ndle) reported

    @realjoebrown @tescomobile 4G on Tesco mobile has been non-existent pretty much all day. Thought there was a network outage

  • anzbmw isv (@anzbmw) reported

    @tescomobile It’s a scam if wife wanted to cancel this contract she would have to pay the contract up in full now is that right.
