Shocking service from Telkom

Telkom throttling my internet line well before I had reached my cap. I have been charged for a 4mb line ever since I have had the internet yet I have never had anything faster than 1.7mb speed. <br> Cant get through to the call centre, just rings forever. when I did get through I had an argument with the technical support person who eventually offered that I speak to his manager, only to be put on hold for another 7 minutes and then they I believe that they put the phone down on me. and no one has called me back. Tired of calling back over and over again, with no solution, getting nowhere and having to repeat my story a number of times.
