Four months later, absolutely no progress or resolution from Telkom!

I had app**** for an ADSL line form telkom in July. After numerous complaints and technicians the installation only occurred at the end of August. I was informed by the technician that the limited speed and cannot get the 4mbps speed services and the speed test show only less than 0.3mps speeds. Despite this, I have billed by Telkom for services since July since for 4mbps dsl. I have called Telkom twice a week to log complaints and disputes since July and till today after a 40min call with Sicelo Jama, I am still unable to speak to a manager or anyone with a mandate to resolve this! I have logged innumerable disputes and have several references numbers but 4 months later remained unresolved without having moved from the original dispute. This is totally unacceptable, I am no nearer to resolving this since July.
