Promise not kept

I upgraded my Telkom line from 4 meg to 10 meg line on the 17th of May and I'm still waiting. The tech at sales said that the order got stuck on the system and now I'm waiting for them to resolve the problem so they can close the order. Telkom promised me 3 times that they will resolve the issue but I'm still waiting and every time the tech promises me that he will resolve the issue but I'm still waiting. They keep on saying that it is stuck on the system all I want is my 10 meg line like I was promised by Telkom. They even said when I did the order that there are ports available but my order is still not closed off on the system. Cam someone please assist me regarding this issue?. Thank you ********** .
