ABSA employees keep cloning my card.

My credit card is being used by someone, somehow. I have reported it and it's been blocked but transactions are going through and its being maxed out every time I put money in to maintain my credit score. I am basically funding someone else's lifestyle. I do not have the money to pay it off so I can close it. I am trying to pay it back a little by little but the person somehow can see that the card has been 'loaded' and uses the money.

At this point I believe that it is someone from absa that's making duplicates of my card every time a new one is issued, because, the transactions start again even before I have collected the card.

All absa can say is that they are investigating and the investigator will call me back but they never do, and the call centre agents never have information for me and I should wait for the investigator. I am really frustrated at this point and I don't know what to do.

My money is going down the drain.
