Cancellation not happening

I sent a request for cancellation of fixed services on 12 October after speaking to service department on the procedure requirements. They told me that I can contact them 21 days from application to find out if cancellation had taken place and if not...to contact them and they will cancel my service within 24 hours. I did exactly that and called on the 21 day deadline only to be told that for fixed services the due time to cancellation would be 30 days. Called back after 30 days to be told I have to forward my original e-mail to ********** After checking and rechecking the correctness of the address...once sent...it came back as incorrect. The next time I phoned...the address was ********** reply .....contract still active after sending the documents. Went to local Telkom office to be told that they cannot assist with cancellation...but can use their phone to speak to the relevant section. After holding on for an eternity the next e-mail request was to ********** Two days later....contract still not cancelled. Last friday I spoke to another service person....sent documentation to ********** This morning I spoke to an new service person....and off the documents go to ********** I also resent the documents to the original ********** address as well for good measure!!!!! How can this company be so hell bent on driving their customers to despair!!! How many more times must I redo the same action before someone pushes that little button for my cancellation. How difficult can it be????!!!!!
