Slow ADSL after line fault

So my line connection has been sorted out. My line speed is now between 2 and 5mbs although i am paying for a 10mbs service. There was never a issue on this line in regards with speed. <br> <br> Now Telkom is pointing the finger at Web Africa saying that you guys are throttling my line thus causing this issue.<br> <br> So now where is issue??? Frankly this is not my problem, Web Africa is doing my line rental lease with Telkom to get the issue resolved.<br> <br> Your consultants are saying a line cannot be throttled, this is bull!!!
