ADSL SPEED

I have complained about my ADSL speed numerous times to telkom via there support line. I am getting only 512 kb but I am paying for 2 Mbps which I never ever received. I have done numerous tests at different times of the day and night but never ever get even close to 600 kbps. <br> <br> They initially recreated my account but this did not improve my line speeds. I then attempted to reopen the complaint but there has been no response from them. I then opened a new complaint but had no response. <br> Below are the support numbers that I recieved for my complaints.<br>
