    @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

  • RachelKendall16 Rachel Kendall (@RachelKendall16) reported from Risca, Wales

    @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?

    FYI @tescomobile have a better phone, better data and price freeze for over £15 per month cheaper than you. I've been a Vodafone customer for nearly 20 years and I'm afraid you're going to lose me now. Very poor form to increase bills to loyal customers by nearly 9% mid-contract
