Instead of fixing my phone they broke my ADSL

Last week I logged a fault with Telkom to fix my phone line - the phone didn't ring when people called, but I could still call out. On Saturday Telkom closed the call saying they'd fixed the fault, when in fact all they had done is make the problem worse - now I have no phone line at all and my ADSL doesn't work. I've tried to re-open and escalate the fault, but it's almost a week later and still nothing has been done.
