Pep can't be trusted with money transfers

Today was a very traumatic day for me at Groblersdal PEP in Jane Furse. The cashier who helped me was Thrudy at 08:40 in the morning. I deposited money at the store and unfortunately the receiver didn't get the money when he went to withdraw only to find out the money was already withdrawn from his account to my surprise myself the cashier and the receiver we the only ones who knew the pin, obviously the cashier was looking at me and memorized the pin while punching it. The receiver called me to notify me about the missing money and I quickly called the number given for enquires only to find out that the money was withdrawn within 4 minutes after I have deposited it. It's clear that this is a inside job because if I was the only who withdraw the money it doesn't take me 4 minutes to get to the ATM and withdraw the money.
