Pathetic IDSL

From 01 Apr. the connection is down. After many calls to the call center fault #29CRK080415 has been created.<br> From today (13 Apr) the connection comming On and Off non stop. When is on, the speed is 24 to 50 Kbits per second. Yes,but this was internet speed 20 years ago.<br> My contract is for 2 Mbit line and i receive 1.2%-1.5% of promised speed. Do i have to pay 1.5% from the bill?<br> Telkom send a SMS - the line was re-tested and found to be free of defects. Don't have idea - who and how come to this conclusion. The satus of the connection was not changed.
