ADSL Internet Ripoff

Had a 2mb/s adsl internet with Telkom for a while and would get around 200kb/s download speed (mostly below), then this month upgraded to the 4mb/s line and package expecting to get around 400kb/s download speed, but now I am not getting anything higher than 220kb/s.<br> <br> So by paying for double the internet speed I am in return getting at most 20kb/s more instead of another 200kb/s. And all the call center said was that they could send out a technician, which was the day after a technician was there so there is supposedly nothing wrong with the line.<br> <br> And in my area there is 10meg lines available..<br> <br> Apparently the minimum download is 256kbps which I see as unacceptable for a 4mbps line, but even that speed is not reached
