Unhappy and dissatisfied customer

I've never been so mistreated as a customer, I was given a gift bought at this store City girl at overport, and only to find out that I don't like the item and when I check on the slip of procedures on a refund none whatsoever had that information assumed I'll go back when I get time only to find out they have a 7 day policy for returns. However as a customer that has nothing to do with me because it was not stated on the slip no one was willing to help and I'm willing to report this issue as I'm still not assisted I left the items in the store and my money that's how mistreated I was. I've never ever in my life received that type of service.
