STOP EXCUSES AND REFUND ME

America Swiss centurion mall. I bought earrings there and now I don't want them Bought them and 3hours later I remembered that their jewelry does not really last. It discolors and the diamonds go brown. And went to get my refund and the lady at the floor said they cant. They don't have cash. I paid with my bank card, and like most shops they refund you back to your bank card. Said they can only refund you if you paid via credit card, for they doesn't have a system like most shops to refund back to your card. I must come back later when they have cash. AMERICAN SWISS A BRAND LIKE YOU REFUNDS CLIENTS ONLY IF THEY PAID WITH A CREDIT CARD? Just refund me and will leave you alone for good.
