    @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?

  • HAndTheElements Hegsy & The Elements (@HAndTheElements) reported from Cardiff, Wales

    @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

  • ArronLP Arron Lindsay Peach (@ArronLP) reported

    @tescomobile Can I please ask you why in your stores you are falsely advertising deals? Why your staff are not trained correctly and feel it is appropriate to lie and why you think it is acceptable to give a customer no choice but to take a deal they don’t want? Thanks!
