Billed for line that I am not/can't use.

This has gone one for 2 months now. I have paid Telkom for the line rental and install. I have not been able to use or connect my ADSL through the line I requested. I have prompted to migrate to a different service provider, the wait is 21 business days to respond to my cancellation of my "month-to-month" contract with them. Now, the problem is, I will get billed now for the 3RD time before I can get anywhere if that is the case. I have NOT used the line at all and haven't bee able to. Telkom claiming its my ADSL ISP that's the problem, but their support(24h by the way) says otherwise. I am inclined to believe them over Telkom as I have been trying to get hold of them for the past 2 weeks now, even went to my closest branch. I will recommend Neotel to everyone I come across. I thought Telkom was suppose to set an example.
