Unable to cancel contract

I used the Cell C web contact form a month ago, to request contract cancellation. Today called the call center, to be informed that it was not done and I have to give another 30 days notice, from today. I said this is not acceptable and requested that my contract be cancelled immediately and number released for porting to another network. They also promised that a so-called team leader will call me about the fact that my initial cancellation request was ignored. After this I was put through to the porting department, which informed me that no cancellation request was logged... this even after speaking to the cancellations dept.<br> No reference numbers are given. No response to requests.<br>
