Pathetic Service

I have finally made a decision to get an ADSL line after having a prepaid line for the past 14yrs. It has been an absolute nightmare trying to get this done through Telkom .Tons of phone calls to the call centre it is now 2 months later and I'm still waiting, now it appears there is a fault on the line. I have logged the call on the telephone, tried the website the only feedback I receive is a technician is busy and will come, so is XMAS coming. I have been inconvenienced for weeks if I had a choice I would never have any dealings with Telkom. Three technicians have been out here and leave saying somebody will return to resolve the problem to no avail. What do I need to do to get this resolved.
