Your cashier is a ***** (Clicks Equestria)

I went to Clicks Equestria today and bought items worth R77.00 which I paid for with R100 to the cashier Thokozani Mahlangu and he gave me R22 change , after having to ask him for my receipt which seemed like he didn’t want to give me I left the shop. When I got home and went through the receipt I realised that Thokozani Mahlangu the cashier had spent my cash back R70 and punched in that I paid R30 for the R7 that was remaining after he stole my cash back , why would I pay only R70 from the cash back when I have R117 cash back. And how could I pay with R30 for something that costs R7 instead of a R20 or R10 note . After realising this I returned to the shop the manager cashed up his register and he was over with R70. The cashier Thokozani came up with stories of how the system (only on his till )was acting up. 1. How can the machine spend my cash back and still punch in that I paid R30. (Would the machine error not take the whole amount instead of choosing only R70) 2. When he realised that the machine spent my cash back why did he not inform me the customer of the mistake. 3. Why did he still take my R100 if his intention was not to *****. 4. Why did he not want to hand me my receipt with the change if there’s nothing to hide The manager did not want to do anything about what the guy did only that he must apologise, which he failed to do. Clicks you can’t have a ***** as a cashier working with people’s money. I will not be shopping at Clicks Equestria while that ***** Thokozani Mahlangu is still employed there cause next time it will be a higher amount cause I believe it is not the first time his doing it. Anyone that shops at Clicks Equestria, Go through your receipts and stay away from that cashier.
