Vodacom I *****ing money

I ended 3 contracts with Vodacom in 2021-09-06. all of the sudden I am being charged for the 3 closed contracts without me reopening anything. I saw on the new bill I got from them that my bank account will be deducted again for the closed accounts \ numbers. I have called the support center more than 5 times they are *********** (I am sorry to say so) but I was told to either doe another early cancelation or they could lower my contact costs. since the third of May someone would have called me to sort this out. I even went back to the Voda-Shop in Irene Mall where I did the payments for the cancelations but they just referred me back to cancelations.
