NEW ADSL LINE - NEVER WORKED

We had a new adsl line installed at a complex that we had just moved into however ever since the installation the line never worked. Technicians come out however they say nothing (I think the technicians have taken a vow of silence) . They just look at the router and disappear. We have called in numerous times rep**** to sms's saying that the line is still faulty however to no avail and the line is still faulty. <br> We are lost and I cannot believe the level of service that we are experiencing in this regards.<br> At first when we paid the deposit (early jan) for the line we told that they would come out however when they didn't arrive in about a month we were told that there are no lines available and then we struggled to get our deposit back. Then suddenly out of the blue the line is installed (27 feb) and here were are. Now we are being charged for a service that has never ever worked. UNACCEPTABLE. UNACCEPTABLE.UNACCEPTABLE.UNACCEPTABLE. FRUSTRATED,FRUSTRATED,FRUSTRATED,FRUSTRATED, PLEASE FIX THE LINE.....
