Unusable adsl line

For the last 5 months I have been unable to use my uncapped 4mb/s adsl line for more than 5 days in a row. Every few days the dsl line is either offline or I have speeds slower than dialup. <br> <br> Every time I log a fault the technicians on Telkom side fix the line and inform me that it will not happen again, but the problems keep coming back. I do not understand why they keep telling me that the problem is fixed when it is obviously not the case. <br> <br> At this stage I have reached the conclusion that Telkom is unable to solve the problems of the high demand of Internet usage and is therefore temporary fixing line speeds for the clients that complain so that they can mark the problem as fixed.
