    @tescomobile Hi, can you tell me if Tesco intends to support Apple Watches any time soon on a cellular level. If not why? O2 network is used on Tesco mobile…. How far apart can an iPhone be away from a watch if used and will your Apple Watch connect to all available WiFi?

  • SuzetteFarrier Faz (@SuzetteFarrier) reported from Hounslow, England

    @tescomobile Again,just an excuse. It was a new phone out of the box-your staff member swapped the SIM card, so it’s not that they couldn’t touch the phone, they couldn’t be bothered to provide any sort of customer service. Nothing is set up on the phone!And she doesn’t know HOW to set it up!

    During a complaint with @tescomobile, they handed over all my personal information included security questions and answers to the Ombudsman. This breach of #GDPR will cost them dearly. I've just finalized a county court filing to recover the damages.
