Super Slow ADSL

Adsl speed only 40Kbps. Phoned Telkom helpline. Had to switch rooter off and on. Then speed of 80Kbps. According to lady on helpline it should be OK now as it test on her side 200Kbps. I told her it is far from 2Mbps. She suggested that she can log a fault but if there is nothing wrong with the line I have to pay the technician a fee of R300. So if it is Telkom throttling my uncapped line in the beginning of the month, there wont be a line fault and I have to pay the technician. I've had this problem before and then there was nothing wrong with the line.
