refund policy gone wrong!

Purchased a dress this saturday from gateway legit store. Took it home, was not suitable. Took it to pinetown branch to exchange for something more suitable, found an outfit that cost a bit more than dress, so decided to exchange and pay the difference. Was told that branch didnt recieve stock of dress and it could not be returned there. Paid cash for new outfit and then took dress to the pavillion mall branch later in the day. Had the receipt, tag was on, purchased it the night before and garment was in perfect conditon but was told that i cant get the cash , i must take something else or take a gift card. This is ridiculous. I had already spent my cash in the other branch earlier when they refused to exchange and now this store had stock and i met the return policy terms but couldnt get my cash back and i was depending on this cash since i paid cash for the other outfit in the other store! This is poor customer service. I now have a gift card when i actually need the cash! It is my right according to your policy that i be refunded as i met all the conditions! Please rectify this and contact me with a solution! My email is [Email Removed]
