Bad customer service.

Okay so trying out Popeyes jabulani mall and instead of a wrap they give me a sandwich. So I kindly return the food and boom a palesa happened to me. She first tells me "so if it's a sandwich and not a wrap you won't eat it?" Then she asks me what is she supposed to do with the sandwiches. Then she throws shoves me back with my fries and onion rings and leaves me there. Customer service zero.
