FNB is unable to stop ongoing ***** on my account

FNB has still not resolved the ongoing ***** on my card. The last I heard from them they told me that I was refunded all the money and that I "should check my statement". No money has been refunded and the culprits are still debiting my credit account every month. What's very worrying is that I have cancelled my card twice and every time they debit my new card. How are they accessing this information? FNB is unable to stop *****. I have now cancelled my latest credit card and will not order a new one.
