Telkom driving me insane

I recently ordered an upgrade on my adsl 10mb home unlimited to a 20mb premium unlimited. The consultant checked if my area was covered for that upgrade. She said it was and the order was put thru. A few days later telkom informed me that my line couldn't handle the new speed and the order was cancelled.

What did telkom do, the cancelled the order and closed my current 10mb package. Got home one day to find my adsl not working as well as my username and password.

After numerous calls at my own expense, I was informed that my 10mb adsl service that I had for almost 3 years was closed without notice and I had to call another department to get it reactivated.

Again after many calls and days later, still no joy and adsl is still not working.. Telkom are truely in competent, how can cancelling an order that was rejected by them also close my current service. If I receive no feedback from them soon, I am going to cancel everything with them and move to another service provider.. Should have listened to my friends and family when they said not to go with telkom because this would happen..
