Mutlichoice Billing System is terrible

I have been made to cancel my subscription every month since April this year. I gave Multichoice a months notice in April, but R607.65 was debited on 9th May 2022. I called Multichoice to point out that my I had cancelled my subsription and that I wanted them repay my money of which they did. I insisted that they cancell the subscription of which they confirmed they did.

On 2nd July 2022 R1176.00 was debited on my account and had to call them again to point out to them that I do not have a contract with them. They simply apologised for debiting my accouunt and they advised me to reverse the money with my bank of which I did.

Again on 2nd August 2022 my account was debited of the amount of R625.94. I had to reverse it with my bank but i am concerned that this is going to affect my creditworthiness in the future. I am frustrated. Multichoice is doing as it fits with my account.
