Unresolved ADSL Line Issues

It has been more than 2 months now that I have reported a fault on my ADSL line. Each time I start to use the internet at night the line completely disconnect. I logged the call with Telkom and they sent someone out after a week or two. The person came to my house without an appointment while I was at work. He then indicated that he could not find any fault (without even entering my yard). I insisted we schedule an appointment the weekend, which he never honored. I contacted Telkom again an confirmed the fault was not corrected. Another Telkom technician came out and called me to inform me that he did find a fault (intermittent fault) on the line but it should be resolved by another department. He said he will transfer the fault to them. They never came to fix the problem.<br> I then went to Woodlands (Pretoria) Telkom shop and again logged a fault (the lady told me the previous fault was marked 'resolved'). Since then I have not received any support or call from Telkom. Except I did receive a SMS saying the fault was resolved, but is has not. But I still have to pay each month without a acceptable service.
