As most seem to experience - the call centre people tell you everything will be sorted out and then nothing happens. My number switch was supposed to have been sorted by the 11th, so I phoned on the 13th and after a 45 min discussion was ensured it would be sorted out by the 17th (not sure why it would take 4 days), on the 17th nothing had changed so just before midnight(to give them the whole day) I engaged via Limechat once more with another person who told me it would be sorted within hours. Guess what, on the 18th nothing had changed so I phoned up, was told things I knew to be wrong, got passed to 5 different people and they assured me it would be sorted by Monday. None of them have a clue and there should be Senior Management liability here i.e. someone should be going to jail based on the number of complaints I see. The service is utterly useless and unprofessional. The trouble is we all need/want phones so we need better regulation with heads on the line to sort this laughable pretence of a service out.
