Telkom Mobile - Promo 5

Hi<br> <br> I have a 10GB 3G Contract with Telkom Mobile, and this contract was to expire in August 2014. I have went to a Telkom store to have this contract cancelled on the 9 December 2014 and yet I am still being debited on my personal account. I should have paid January 2015 my last payment and yet I am still paying for a contract that I'm not using. I have phoned 3 times and yet I only get a reference number every time. All I ask is for the contract to be cancelled.<br> <br>
