Telkom not responding to a fault

I reported my Telkom line as faulty a week ago. I have no internet access and are unable to do any work at the moment due to this. Telkom does not send an update or tried in any way to get the DSL line repaired. the contact centre says their is nothing they can do as the technicians are very busy - poor excuse, hire more people. I am being billed for a service that I am not receiving. Ref no 228CTZ090116.
