1st adviser unhelpful when trying to switch to sim only . 2nd adviser arranged a good deal so I agreed to stay . Nothing happened , called to see where my sim is to be told that the deal I had been promised was not possible. I complained and asked for the call to be listened to ... I missed 2 of the callbacks while at work, and you cannot call them back , waited all day the next day but they never attempted to call me back at all , and the 2 gentlemen I spoke to Mark and Richard did not seem to care . Still awaiting a call back still have not got my sim only deal . TERRIBLE . I have been a customer for over 13 years
