Disrespectful and Unacceptable Behavior

I am so disappointed and disgusted. I visited the Cotton On store at the Glen shopping centre today to return an item I had which was unsuitable. I requested a refund but was told they cannot reverse a purchase on a debit card which I understand but when I requested a cash refund, they said sorry they do not have cash in store. They said I must choose something else for the value of R 600 but I couldn't find anything suitable. The Cashier called the supervisor who extremely rudely and very disrespectfully told me They don't have cash and I could go to Mall Of the South for a refund. When I told her that I had to get back to work, she very sarcasticly told me that she could then refund me the R600 in R5 and R 2 coins??? Really, this treatment was unacceptable and everybody in the store overheard her. I feel embarrassed and very angry for being treated in this way as I purchase most of my clothes from Cotton On and I don't deserve such disrespectful behavior. I just took my goods and left. Seriously.... R 600 purchase refunded in coins????
