Telkom Does Not Care - Lies & Bad Service

I have a 24 month 10MB/50GB ADSL contract with Telkom. In early August I began experiencing very slow internet access & speeds. I am getting only 0.5MB download/upload speeds and noise interference on my landline calls. I initially reported the fault to their call centre in mid-August and after numerous follow-up calls which took many hours of my time, my problem has still not been resolved. In fact on more than one occasion I have been told that the Telkom technical department has closed my fault report as \being resolved". Each time I have disputed this because not once has a technician come out to my residence to check for faults since I first reported the problem"
