I want my refund

I had several contracts with cell c before and I have made payments timely and finished all contracts on time and also paying cancellation fee at the end of every contract. In 2019 ported my number to Telkom which went fine... All of a sudden around February 2020 cell c, out of nowhere (no conversation), started debiting my bank account. I sent an email and they acknowledged it with a reference, I sent all documents they asked and they promised me feedback after a certain time but instead weeks later I got an email asking me to rate them. I went to the store in Campus Square the manager(Darian) was on the phone for hours and the call cut and he said ***** dep will call me in a few days and it never happened. I went to the same store again and was advised the call made the last time I was there is not showing and I should call the ***** dep myself. I called them and the consultants did not know what to say once I told them that I know about cancellation fees and I have paid all of them. ALL OF THEM KEEP ASKING ME FOR THE CELLPHONE NUMBER FOR THE CONTRACT AND THERE WAS NO CELLPHONE NUMBER BECOUSE I NEVER AGRRED TO A CONTRACT. Subsequently I get told I am being transferred to another department and the call cuts! Highly ***********, its like no one knows what they are doing. I need my refund
