Pick n Pay review: Fraud

I'm not okay. On Monday I sent my helper to pick n pay Birchleigh North with card to buy a few items. I didn't know she had never used a card before. The items costed R134 only. At the till she handed over both the bank card and Pin to the till operator. The till operator put the card on the machine and she is also the one who punched the pin. My helper then left the shop

1 hr 30 mins later I started receiving messages from the bank about transactions that have been made. There was a purchase of alcohol from Tops which was R16 000, a withdrawal of R3 000 and other items. Altogether the money that was used was R21 000. We quickly blocked the card. In trying to figure out what might have happened we realized the card that our helper had returned home with was not even ours. We went to the shop presented our case to the supervisor expecting them to reveal the cctv footage.

At first they said the supervisor with access to the cctv room is not on duty but they will check and send to us via a video recorded.

On Tuesday we went to the shop they refused to reveal the footage. Up to now they are refusing.

Help me guys what do I do next. I'm not okay.
