Street Style Store — Regarding my order return and refund

Website:

I ordered 3 products from SSS online and prepaid whole amount. Now when it was delivered, I found even the XS which I ordered was large enough for me and their products do not have size smaller than XS. Hence I tried returning the clothes but there WAS NO OPTION TO RETURN. ONLY EXCHANGE OPTION WAS THERE. THIS IS SO PATHETIC. AND I tried using exchange option once now. And still they delivered again said cannot be refunded. I HAVE NOT EVEN USED ANY CLOTHES THEY ARE PACKED LIKE THAT AND THEN IT'S PREPAID . SO PATHETIC THAT YOU GUYS ARE NOT EVEN REFUNDING MY MONEY WHICH I PREPAID FOR YOUR ORDER. I WANT MY REFUND ASAP. I'LL USE NEGATIVE WORD OF MOUTH FOR SURE FOR ALL MY RELATED PEOPLE WHO USE YOUR APP AND ORDER IF THIS IS NOT RESOLVED.
