**************** at Pick n Pay

I went to pick n pay at protea Glen on Saturday 9/11/19. I bought orbit mint gums and requested a R200 cash back. I was helped by a cashier by the name of Emmanuel Nemakundani. After I put in my pin number in that machine, I took out my phone to check the balance. While I was busy on my phone Emmanuel took out R200 and a slip. I got shocked when I saw my balance,he then said he made a mistake. I said what mistake,he said he 'mistakenly' punched in R500 instead of R200. He had R200 at that moment I'm his hand so I took it with the slip he had wanted to check if he put in R500 for sure. The slip he had was of large carrier bag time on it :15:09. He took out R200 from somewhere and R100 from those red/brown plastic bags they have. I then requested that he give me the slip for withdrawal,he did and the time on it 15:08. If I did not check my balance at that moment I wouldve left with R200 while he took my R300. Why was I given a wrong slip of a carrier bag I didn't buy to make me think its a withdrawal slip? I took up the matter with the floor manager, waited for about 40 min while they "investigated" only for them to come back and tell me that Emmanuel made a mistake. Why are we being ****** like this by cashiers? So many people are having their money taken away from them without knowing. This should stop,I'm very unhappy with how the manager handled the matter
