Myntra.com — Wrong item delivered but delivery person refused to pick the same as return

You guys have a pathetic service for product return and pick up. I RECEIVED A DRESS INSTEAD OF A JUMPSUIT AND THUS RETURNED THE PRODUCT. MY RETURN IS NOW PUT ON HOLD BECAUSE THE DELIVERY PERSON REFUSED TO TAKE THE RETURN AS THE ITEM RETURNED DOESN'T MATCH WITH THE IMAGE. FUNNY BECAUSE IT'S THE SAME REASON I'M RETURNING THE PRODUCT.. HOW CAN I not get the refund because of the same??????
THE CUSTOMER CARE IS OF NO USE. THEY ONLY KNOW A FEW TECHNICAL TERMS JUST KEEP SAYING THEY'RE LOOKING INTO THE MATTER. IT HAS NEVER HAPPENED WITH ANY OTHER SHOPPING SITES.
