Battling to Cancel Contract since 20 September 2017

I sent through my cancellation form on 20th September, re-sent on 09th November requesting if it had been cancelled, I got no response. I have now called a few times, I can't seem to receive any straight answers. I managed to speak to one helpful lady on Thursday, I re-sent the cancellation. I have still not received any response. I just called again, with absolutely no luck and get told someone will call me back. a debit order went off the 02nd November and The debit order which went off my account on 01 December was for R 781-52. They billed me for the annual licence fee which was included in that amount. I am really at my wits ends. This is not the time of year to be doing people in of their money. Very bad service indeed.
