Telkom and moving line: TERRIBLE

Telkom is truly terrible. We knew we were going to move residence so we requested a line transfer early December. We were supposed to get a call back when it was completed, and never heard anything. I then phoned again just to be told they are waiting to confirm the address. I phoned again to hear of progress and the operator told me they have put it on as urgent, and confirmed the new address. I phone again, just to be told that suddenly they cannot find the order, and they will phone me back. Never heard anything. Phoned again today to be told a senior consultant will contact me, again, nothing. I was also charged for December even though we were no longer using the line or internet. DISGUSTING!!!!! Please do something about this, your service is **********. I refuse to make any more payments until the line is moved.
