HOW DID MTN TAKE R479 FROM MY CREDIT CARD NINE TIMES IN TWO DAYS? WHY DID I GET NO FEEDBACK AFTER LOGGING THE ISSUE?

I bought the Super Flex 10G data, unlimited calls and SMS contract online for my son, thinking that is a contract, as nowhere does it state that it is a pre-paid “contract”. When he needed extra data, we changed to the Super Flex 20G data for R479. I think it was the 13th of May, as then the problem started!!!! Between the 13th and 14th of May 2024, R479 was taken out of my credit card NINE times, adding up to R4311. How this happened, I am not sure, as I definitely did not authorise the payments! We phoned MTN 135 number numerous times asking them to please refund the money, with no success. No one from MTN came back to me, as I gave my cellphone number as contact, mine is a MTN number as well. I do not have R4311 to spend, and I really thought by this time, I would at least have had some feedback, I mean it has been weeks. Further, I cancelled my sons old contract that has been going for over 24 months, I gave them a months notice per mail and still that debit order kept on going off! PLEASE be carful when buying a Super Flex “contract”, as MTN DOES NOT GIVE YOU ANY SERVICE !!!Q!
