ADSL and Axxess

I have logged a fault with Axxess on 23/02. My ADSL line is riddled with problems. A simple line test will confirm this. However, since Axxess is my ISP, the faults get logged through them. It is now going on two weeks, and Axxess says that since there is activity on my line, they closed the ticket and Telkom also reckons that \working"is good enough. My line runs at 1700 and uploads at 230. It should be 2048 and 512. It has been like that up to two weeks ago and has not improved since. Telkom has a 30h SLA with Axxess"
