Double Charge

Today we went shopping at Clicks. At the first till, after entering my pin, the system froze and I was moved to the next till. After another two attempts I decided to try my debit card instead of credit card and the transaction went through immediately. I received a SMS from my bank as proof but the slip didn't start printing. The manager then told, not ask, me that they need to do the transaction again not explaining why we needed to do it. I showed him the SMS from my bank and he didn't seem to be bothered at all. He then told me that I need to check my bank statement and come back the tomorrow. I informed him that I am not from PE so it would be a huge inconvenience. All of a sudden that was not necessary and would the money be reversed by Wednesday. I am very disappointing in the manner the manager treated us with no respect and dehumanising me. What if I declined or did not have sufficient funds? No apology, No respect.
