Unhappy customer

I am not very happy with Home-Connect at the moment. I was misinformed about the process when moving homes and my line, thus ending up to now pay for a line I am not using at all. I requested the activation of my new line for 1 November, this was requested in the beginning of October already and now 4 days after the requested activation date all response I am getting is we are awaiting feedback from Openserve. I have not received any proper feedback as to what is going on, when I can expect my line to be up and running. After 4 years of being a client I am not very happy with the service.
