Rude staff at the boulders shopping center midrand

was very disappointed today at one of your store in midrand I tried to pay account at sheet street the boulders shopping center midrand ,the staff told me the way get off because I cannot pay Mr price account at sheet street, she cannot deal with Mr price customers its either I make a way to buy something cash at sheet street or she's not accepting my payment, they told me sheet street boulders midrand they not part of Mr price group, when i open account i was told sheet street and my ladies are part of Mr price.now im being chased and go look for Mr price . I was advised that Mr price customers are not sheet street customer i must buy cash first.
