Telkom ads sucks

My adsl line has been faulty, it works for 5 min then loses signal and is off for 5 min. This happens continuously! I logged my fault on the 18th of September, I've called them daily and this issue still hasn't been resolved. I'm still paying and being charged for this fantastic line. All I want is for this to be fixed. This is what happens when you have employees who are not skilled enough to resolve an issue or have enough knowledge, at least tell me what the flip is going on in terms of progress!
