Bad service from Vodacom

Maybe somebody would be able to assist me. I had a contract with Vodacom, which was suppose to expire last year June/July 2021. I did the necessary arrangements with Vodacom to stop this Contract. To my surprise they kept on deducting a premium. In December 2021 I phoned *** on the 9th and they promised me that they will stop it immediately and write back the premiums. On the 30th it deducted again and I phoned *** again. Please take note I did it more than 3x times explain my issue and every time I got cut off, just to phone again and again. At least I got through and the lady Nomelo promised me it will not deduct again and that they will refund me as soon as possible. I even got a ref. no. 1/***4 982. I was never refunded nor was it stopped, just to deduct every month again and again up to now. Struggling to get hold of the *** and even the other numbers given on google, I decided to reverse the premiums each month on my banking app. So did my amount owing just went up and up and this month I coundn't stop it on my app and had to go in to the bank to do a stop order. Yesterday I was informed that I have been placed on ITC by Vodacom, which is unexceptable for me. I went to a Vodacom store and to my surprise they could not even helped me. According to them it is an outsorched campony handling the cancellations and it happens all the time.. Guess what was their advice to me to be helped!! Hallo Peter.. Can you believe it.. Please help if somebody can... I know there are recordings a Vodacom or so they say.. Please listen to my plea everytime made to them, but with no success.😮💨😪
