Cancel my contract!!!!

<p>Please tell me how do I once again cancel my contract ACC ********** 99 and nr ********** with Telkom Mobile??????? I submitted request for cancellation in store at Festival Mall on 22 April 2016. After that got billed again. Phoned customer services and they said no cancellation request showing on the system. They advised me to fill in the form once again and mail it ********** which I did on 13 June 2016. Once again got billed after that and phoned in ONCE AGAIN and they told me no request for cancellation has been logged. On 27 June 2016 I spoke to a lady and mailed it to her while I was on the phone with her and she confirmed she received it and would send it to cancelations immediately. I mailed ********** Yesterday I phone in ONCE AGAIN and guess what.....AGAIN being told that no request for cancellation has been logged!!!!! HOW DO I CANCEL MY CONTRACT as I am getting ******* and getting billed for a line I'm not using. Please cancel my contract and refund me my money you've been debeting off my account that includes the "out of contract extra charges"!!! I have all the proof that i've been trying to cancel this contract. I had a similair issue last year with a tablet deal also with Telkom Mobile. This is the reason I am cancelling all my contracts with Telkom mobile one by one!!</p>
