Over charged during swipping

My Name is Reuben<br> <br> On the date: 20-11-2015 at about 17:45 my wife went to Spar at Bopedi (Nkwana Plaza) to buy grocery. Returning back Home, She looked at the till slip..grocery cost R833.18 and (change R100) all adding upto R933.18. She never requested extra cash from the cashier. She had to go back to the store. Reported the case at the Customer sales. They checked the slip and gave her R100.00 back. nothing was said back to us about the ********* behaviour of their Cashier. <br> <br> Till # 019<br> Cashier # 323<br> Slip # 2398<br> Time #17:45
