unauthorozed debit order

My question is, "Who approved the debit order/changes"? ON 25/10/24 AN UNATHORIZED DEBIT ORDER WENT THROUGH AT AROUND 02:14 AM. AS SOON AS I SAW IT I GOT IN CONTACT WITH A CONSALTED ON WHATSAPP BUT THEY TOLD ME I COULDN'T REVERSE IT AND I SHOULD GET IN CONTACT WITH THE COMPANY, I TOLD THEM I HAD NEVER HEARD OF THIS COMPANY OR SIGNED UP WITH THEM, WENT TO THE BRANCH BUT THAT WAS EVEN WORSE, AS THEY GUY WHO WAS HELPING ME SEEMED NOT INTERESTED IN HELPING ME ALL HE DID WAS SAY I NEED TO CHANGE MY CARD BUT THAT WON'T GURRANTEE THAT THEY WON'T DEBIT AGAIN, I WAS CHARGED R70 PLUS THE FEES FOR CHANGING THE CARD ON TOP OF LOSING MONEYAS TEHY COULDN'T REVERSE IT.

I MOVED TO ASK OTHER BANKS WHAT WOULD THEY DO IF ONE OF THE CUSTOMERS CAME WITH THIS MATTER, AND I CHOSE THE BEST BANK WITH THE BEST ANSWER, KNOWING MY MONEY WOULD BE SAFE. AS CAPITEC DOESN'T CARE ABOUT THE SAFETY OF MY MONEY
