Mr price home gateway

Very bad customer service. I asked to talk to the manager she came and she never great she told the stuff is she the same customer you were talking about like I am subject next to her and then she told me I understand you are not stupid. I bought set of plates and I asked the stuff if it’s on promotion and she said yes ,at home I realize That I paid full price and when I came back they made me look stupid. If they had the sign in the wrong place why they make us I will never go back to that store again
