Paying for 10MB ADSL, recieving 4MB ADSL speeds

I'm currently renting an 10MB ADSL Line from Telkom. I'm on a different ISP. I've have logged a fault with Telkom on the 20th of March. I've also called to check the progress of the fault, where the operator told me that there is a problem with the exchange and that a technician is busy with repairs.<br> <br> It is the 27th of March today, and still nothing has been done to solve the problem with the exchange. Meanwhile I have to keep paying for a service I'm not getting. The ADSL situation in Potchefstroom just seems to go downward more and more by the day.<br> <br> My Fault No. is: 212CTK200316<br> <br> PLEASE ASSIST
