ADSL line down, USELESS TELKOM!

My ADSL line has been down for over 2 weeks now. I've been in contact with the call center, spoke to numerous people. I even have a supervisors 2 cellphone numbers and his email, but still I don't get any feedback or time frame on the fault. The fault has been escalated, re-logged but to no avail. My voice line is also intermittent, so I'm paying for a service that I'm not getting. Even my ISP has escalated the issue, and they don't even know what's going on. fault numbers : 517CRK020116, 112CRK130116, 1154CRK180116. Escalation REF NO : 807907
