Makro customer service disappointment!!!??!

I’ve visited Makro Cornubia today to purchase a few items. I cashed up at teller 38. My purchase was successful however, the slip was printed blurred. I was in a rush due to exceeding my break and asked for the supervisor to approve my slip to leave the store which was ignored. I was spoke to very rudely and had to wait 30 minutes to leave the store after I have paid for my goods. The manager have even forgotten about my reprint and a family member of mine had to go to information to request a reprint. I am extremely disappointed with the service I’ve received today. I was late from my break and received a written warning which means I’ve now lost my commission for the month. This is not acceptable!.
