Cancellation nightmares

I have been trying to cancel my account with telkom from the 12th of October and was told that my line with the ISP was still active which is fair, however I have been trying to submit a cancellation request for the better half of the morning and after holding on four a good 30 minutes I was told to email ********** which returns an undeliverable to the service department due to their mailbox being full, which clearly means that the cancellation department is not receiving any requests. This obviously negatively impacts clients trying to cancel their account for whatever reasons. I then figured out to submit a cancellation request online, of which there is absolutely no information on the internet, luckily I tend to play around till I find what I need. The only problem there is all I receive is an error message that states "Unable to complete your request" with no further information.

This is utterly ridiculous, are we to be charged for the inability of the biggest telecommunication company in the country to offer a simple service of cancellations?

When will the service be back up and how are the customers to know what is going on and how to get around such inconveniences ??
