Slow sync speed keeps coming back

Telkom has set my sync speed back down to 2.5Mbps YET AGAIN.<br> I was getting 3.6Mbps and above until late Dec, and ever since then Telkom has been setting my sync speed to 2.5Mbps when I pay for 4Mbps. This is UNACCEPTABLE!<br> How many time do I need to complain to get it fixed?? I am on the verge of cancelling cos I cannot use the service like this.<br> The technician said there was a fault with the cable, then the call suddenly gets closed and nothing was done. Same problem over and over again. I am so happy i chose to be on a month-to-month so that I can cancel any time.<br> 1440crk221215<br> 368CRK241215<br> 62CRK220116 <br> SM181247
