Slow speed with no vested interest to resolve it

On the weekend of 27 August I started to notice that my ADSL speed has DRAMATICALLY slowed down. On speed test earlier I could get 1,8MBPS easily now I could barely get ,2MBPS. I reported it by phone to WebAfrica on the 28 August. It was then reported to Telkom that there is a fault on the line the same day. I noticed on ! October that there is no ticket open on WebAfrica's side and insisted that they open a ticket. When ever I contact them they say it is a fault on the line and Telkom should fix it... that is another report all in itself! They have NO vested interest in having the fault corrected since they will demand their full payment for \services rendered"with me having NO service! After 17 days still no resolution in sight!"""
