Bad customer service and and attitude

I am reporting a bad service that was rendered by Lebogang from Puma outlet Kolonade, this lady made me pay the same item twice and I only realized it when I got home, the next day I went back to the shop and explained what happened, without any apology and with an attitude she credited back my money and took back the other item that I paid for, when I got home one item was missing, I really don’t appreciate this kind of stupid mistake that she continues doing because money is involved, driving back to the shop it’s costly and she didn’t even had the decency to apologize for her mistake which I think it’s something she does to customers who don’t check their slips, this is unacceptable at all.I doubt if this lady was trained on customers service because the staff confirmed she’s a manager, her attitude truely confirmed that she doesn’t have leadership, listening and communication skills instead her co workers were able to understand the situation and helped, she has a BOSS attitude and I feel sorry for her team
