My mum wanted to take her home phone number with her when she had to move out of her home. We set this up three weeks before and checked a number of times leading up to the move that this was still ok. She moved on the 15th December. She is elderly and has no other form of communication. We are still waiting for the phone line to work. There was a phone line at her new house already so no major works were involved. 8 days later and still nothing. I have phoned twice a day every day and I am promised call backs , I have been told that emails have been sent to supervisors I have been told that they won't go home until they have got an update for me . We are on this blah blah blah. Not once have I received a call.
Disgraceful
