Myntra.com — Not returning my air jordan shoes order

Myntra sent me shoes without any box and any mrp sticker. There was no box and the mrp sticker is attached on it therefore I have no mrp sticker. They are not accepting the return request stating that I don't have mrp sticker. It's been 1-2weeks I have been following up with Myntra support. The return team gives me same answer again n again not even contacting over a call. And the normal customer support are so dumb that they don't even listen and just state the mail sent by return team. I need help with this return. Myntra is just trying to scam
