Agro Manager at Honey Junction

On Friday 31 August i went grocery shopping at Clearwater Pick n Pay. Everything went well and i received 7 vouchers each to the value of R20. Meaning it was R140 in total. The lady told me that the vouchers are only valid until Sunday 2 September. On Sunday evening at around 18:50 i went to Honey Junction Pick n Pay in order redeem my vouchers that was worth R140. Once at the till to i gave my vouchers to my cashier whos name is Pretty Gurure. She scanned my items which totaled R196.97. With my R140 vouchers, i was to pay R56.97. However there was one voucher that was not scanning. Pretty tried by entering the barcode in a number times, i really do appriciate her effort. My wife also tried a few times. I was now standing at this till for about 15 minutes just trying to enter the barcode in for my last voucher to work so i could pay my R56.97 and leave. The manager was then called. Not sure of his name because he refused to give it to me nor was he wearing a name badge which i would think is policy. He then says "its not his fault and there was nothing he could do" he then tried saying that the voucher does not belong to my smart shopper card number which it clearly did. The cashier Pretty and another sort of manager even confirmed to him that the voucher matched my smart shopper card number. Only after that he said he will deduct the other R20 so i can leave. He then kept walking up and down past me bumping me and making ugly comments. Which cctv can prove if investigated or looked into at all. I said to him that i will not return to his Pick n Pay. He response shocked me, he said "thank God, i wouldn't want to see you anyway". I took my packets and left. Just want to inform others of this manager as he will take a customer on and actually throw ugly comments...instead of trying to solve the situation and remain calm. He was getting so angry that i was affraid he might want to fist fight me. Anway, hope something gets done about the manager that was on duty. His attitude is very bad and has now customer service s****s. Pick n Pay... please look into this as he even said to me that he is not worried or affraid if i report him. This can be confirmed by Pretty who is the cashier. She even shook her head in disgust. I asked what hid name was and she was affraid to give it to me. So much for my and I enjoying spending our vouchers.
