So called 10mb line

I have upgraded from a 4mb to a 10mb about 2 months ago, since then I have been struggling with intermittent internet drops, I live about 1km away from the exchange and I have made 6 different attempts to speak to the call centre, if the right person is not there to fix it , they will supposedly phone me back, which never happens<br> <br> Come now guys, can it really take 6 phone calls and 2 months of struggle to get this fixed.<br> really disappointed, AGAIN(Not sure what else I expected from telkom)<br>
