  • FayyazUK Fayyaz (@FayyazUK) reported

    Last three days, I have been out of service, with no voice calls, text messages and no data. I spent hours and hours speaking/chatting with support and was unsuccessful. @O2 @tescomobile

  • MrsDanielleD99 Danielle (@MrsDanielleD99) reported

    @tescomobile So this gets better. @tescomobile know of existing problems with SIM cards that can’t show CALLER ID/no voicemail, can’t fix it and continue to sell contracts. Weeks for them to admit, still no fix. Forced to cancel contract now charged c£800 cancellation fee. Surely a joke?

    @tescomobile appalling "service". Been waiting since 2nd Feb for a PAC code & despite 11 calla to you, been told another 3 days before it might be resolved. Shocking. Will be cancelling my contract.

  • madibreach Madi Breach (@madibreach) reported

    profoundly deaf and reliant on his phone (which is linked to his hearing aids) for communication. Do they care NO ONE JOT!! Never again - not if they were the last mobile supplier on the planet. #awfulcustomerservice #theyreallydontcare @tescomobile #worstever

  • yoojungsqueef knickerbocker glory (@yoojungsqueef) reported

  • jeffwhisky24 Jeff Whisky - Slapper (@jeffwhisky24) reported

    @PadWhisky @EE It is awful. The fact they have to increase it beyond the inflation amount seems wrong. Will be gone as soon as possible, most likely moving to @tescomobile

  • vannerbird ☀Ange☀️ (@vannerbird) reported

    @tescomobile No I haven’t Rob. As that’s an O2 site I thought maybe I’d have to be an O2 customer to do it.

  • ianpgraham Ian Graham (@ianpgraham) reported

    1/2 Partner trying to port mobile from @EE to @tescomobile - complete farce. Incomplete process now into 2nd week. Handset not connecting to network, no calls no SMS no Data. She will be staying away alone at end of week with no means of communication.
