Question for American Menswear

Hi how can your chatsworth branch rob me for a pair of white boots.i ordered for R850 and when stocks arrived it was marked for R799 and I received the boots on the same day.
I need a query to take place. As this is a customer being robbed by reputable company.if you cannot sort this out please give me email of head office. I spoke to cashiers they refused but was more concentrated on a connection that brought in a child.
