Telkom still hasn't fixed my problem

I pay for a 2 mbps line and at the moment I have 168 kbps download and 1154 ms ping. I have complained numerous times to Telkom but they still have not fixed my problem.<br> <br> Everytime someone gets back to me about this problem they just stop responding, so either Telkom couldn't be bothered if I have service or not or they can't fix the problem. They are absolutely useless but I must still pay for them to do nothing.
