Telkom ADSL cant even supply respectable speeds

Hi,<br> <br> I have had the Telkom repair team out about 10 times to resolve the low ADSL speed, it is so bad that I cant even run Speedtest to get results it is so slow, so much for a 4 mbps line. Its amazing that this is their core business and they cant even provide proper service, it doesnt matter raising a fault because the technician just changes the line and says that there is congestion on the line.<br> <br> So painful and there is nothing to be done to get any further. Cant be that hard to upgrade if there are so many customers suffering bad service.
