Bad service

I went to Pick 'n Pay Midway mews Midrand on 15/04/2023 around 10:30 am to buy grocery ,while busy paying the till machine went off and when I check on my bank App the transaction already went through and the cashier advised me to make another payment as the bank will refund my money.I did not receive the receipts for that transaction of R235.83.I had to re swipe my card since I needed the grocery ,which I made a payment of another R235.83 because I needed the grocery and I am concerned with the representative respond that there is nothing they could do because if I don't make another payment they will be giving me grocery for free,which I failed to understand ,a customer should rather be stranded the whole weekend without food waiting for bank to refund my money,whereas it was not my fault that their machine are always faulty ....The service was very poor and I am asking myself if I came there with my last money to buy food and the incident happened ,I was going to return home without food?Supervisor on duty confirmed that the machine are always not working and it is inconvenience for customers. It really shows that they don't care about the people who brings money to the business ,I am really not happy at all.In this economy where am I supposed to get extra cash just idling in case Pick pay Machines become faulty, for me to pay double payment. I am a regular shopper there as I stay closer to the store but at the moment I am not convinced that I should continue shopping from them. I received a receipts for my 2nd transaction from Reneilwe Sekele.

Poor cashiers are expected to convey the messege to clients 😢
