Myntra.com — white and black sonaki cups order no[protected]-2076601

Address: 188- A, TOP FLOOR, NEHRU VIHAR, NEW DELHI, New Delhi, Delhi, 110054

I ordered this set of cups on 18 july and received them without any pre msg and after receiveing i wanted to return it there was no barcode so i could confirm the delivery so i asked th delivery boy who came to deliver part of the same order to take this product back and confirm it he said ok mam .now neither he returned to me nor the warehouse received .and when i asked abt the refungd they blame me for giving it to him.i just want to know if im at fault is that not myntra 's fault to train them not to take any product, would i still forcibly give him.i gave him coz i knew he was from myntra .i want my refund.
kindly look in to this matter this could happen with other customers too and plz remember i gave it to myntras delivery boy and i hopethey have the record of who delivered what product
