Terrible Service

I have reported a fault on my line multiple times now, and it still has not been resolved, my line is very noisy and internet is intermittent and the latency is up and down the whole time, i have tried phoning 10210 to find out the progress on my line, i spend 40 to 60 mins each time and no one answers. I have tried escalating the call but still no one has come out, and no one has contacted me. I have asked my isp also to log the call and followed up with them and they say telkom has closed the fault which they opened. This is extremely unacceptable service
