3 Months. No internet. Shocking customer service.

I signed up for an internet line at the beginning of February. It took two months before getting any feedback. Nobody contacted me about doing line installation, and eventually when this was done, the line was FAULTY. I have not been able to connect all month, yet I am being sent bills for services that I am not receiving. I can NEVER get hold of the call centre, and when I get through to customer 'support' via Twitter, they LIE to their customers and DO NOTHING about it. 3 Months. Still no internet. Shocking customer service. This is totally unacceptible. Fault number: 149AWK040416
