Bad treatment

I am very disappointed at how I have been treated by Peter at Woolworths store at Engin in Beacon Bay. I went to buy two items and I paid for them, the payment went through but the receipt could not print. Peter was called to solve the issue. He then said the payment did not go through, I downloaded my statement and showed him. He still did not believe. I was kept in the store until I was made to pay again. I paid again for the same items and guess what the receipt for the for first transaction came out confirming I had paid. I told him how this lack of trust and imp**** *****ing made me feel, he refused to apologise and acknowledge the problem was on their side. Only the black cashier apologise which makedme think if this Peter is not a ******.
