Terrible Service From Telkom

Telkom came out to install a new line at my neighbors house and since then my line has been dead. This happened 5 weeks ago. For 5 weeks I've had no phone or internet connection. Each time I call to find out what is going on, they escalate the call. Problem is, it's being escalated, and escalated, and escalated but in 5 weeks absolutely nothing has been done.
