20 meg line 0.6 meg upload speed.

I have had a 20 meg line with Telkom for 4 months and during this time I am yet to enjoy an upload speed of more than 1 meg. I confirmed with a Telkom representative that if I have a 20 meg line I an suppose to get an upload speed that is half of the download speed (10 megs). I logged a fault, but I have not faith that it will come to anything. Additionally it seems that every time a new customer in my area signs up for an ADSL line, Telkom allocates my port profile to that new customer and I end up getting a higher latency with a much reduced download and upload speed, and I have to call in and wait 30 minutes on the line, just so they can change my port profile back to what it was originally. This is ridiculous and I am tired of having to chase after something I pay for!!!
