    @O2 is there an escalation phone number for you in the UK please? I've tried for 2 months to have a simple query dealt with. Your call centre staff can't/won't help. Platinum customer if that helps. (It shouldn't, but apparently it does) Thanks in advance ,

    @virginmedia @O2 @Ofcom I am unable to get the advertised speed boost via volt as the virgin v4 hub is oos and being held for new customers. They have told me there is limited availability, however as a loyal customer it seems I am not entitled to it. This needs looked into.
