0.3 MB per second for the last 3 months

Im frankly sick and tired of Telkoms ****!!! I have an adsl line that hasnt been able to reach 1mb/s since I got it, evens though it has a line speed capability of 20mb/s. I have had an technician out numerous time and they cant seem to find the problem, I logged a call about 3 weeks ago, and got an sms just that the call was closed....just like that? no feedback, all it said was that my problem was resolved, what a load of BS!!! I really don't know what to do anymore, each time I call the call centre I wait no less than an hour on the phone, and after I've waited the hour I just get cut off!...do we really need to tolerate such service just because telkom has the monopoly? I have a speed test for every single day since I have my telkom line, and the majority of tests are under 1mb/s. I am now officially lodging a complaint against Telkom with ICASA if I don't receive feedback from a senior person within the next 3 days. !!!
