Terrible experience trying to cancel a Telkom contract

I have been trying for over 6 months to cancel my telkom contract....

I have recently moved to the USA and needed to cancel my Telkom contract which I had to leave to run its courae in SA. I was given a form to complete and send through 2 months before the end of the contract and given an email address to do so. Not only have I never received a response to my cancellation email despite telkom themseleves stating that my contract WILL be cancelled 60 after sending the email, but I have since been reffered to about 3 different email addresses, none of which have yeilded any response. I have had to resort to social media (facebook) to get a response from Telkom, but again, this has just meant that the social media team has had me running around sending emails to millions of full inboxes or dead addresses.

I have stated numerous times that I WILL NOT pay any fees to telkom beyond the initial term of the contract as i dont see it as fair to have to pay for their incompetence and have been told that no-one at telkom can find the emails i have sent.

This all seems like a bit of a **** to keep me in my contract from a company which promises excellent customer service but fails at every single turn.

I am extremely worried that telkom will continue charging me for this contract and will blacklist me for non-payment which at the end of the day will leave me with a huge fight when i return to SA to have my name cleared. For a "proudly South African" company they seem intent on prividing more and more reasons why the good people of South Africa should get away from terrible local institutions like themselves.

P.s. I can almost guarantee that telkom will respond to this with another "Apologies for the inconvenience, please send your forms to this address."
