Someting easy as an upgrade becomes a nightmare

For some reason Telkom is unable to upgrade my ADSL line from 2mb to 4mb. i called in a 5 times to there sales division and both times they said they have submitted my upgrade, the third time they said there was something wrong and they logged it to a support team, however i called again to there technical support this time, they advised that the order is there it just needs to be pushed through, called sales again, something was wrong with there systems and was told i'd get a call back, i don't know how slow there systems are but its been been hours and nothing.

All I wanted was an upgrade, how did it come to be 13 days of waiting and calling?
