ADSL Line not repaired for over a month

I have been experiencing problems with my ADSL line from 14/12/2015 until present. I have reported the fault numerous times which resulted in many visits from technicians to my home to try and fix the fault however with no luck. The last technician had told me that the problem is a result off me being too far from the exchange which has resulted in an intermittent line. However, I have had the line for more than a year and it has been working perfectly until now. During the past month, no one has been able to sort out the problem and are still expected to pay for a service that I haven't received. This is absolutely ridiculous as I have had no internet for over a month. Customer service is very disappointing.
