Myntra.com — Damaged product received no return or exchange

I received a damaged shirt (Campus Sutra Men Blue).
Then I asked for an exchange and the delivery boy came for the exchange and asked me to file a complaint about it because it was damaged, then I requested a call from Myntra, they called me and said that it Will resolve in a few days. And after a few days,
they said "We will be unable to accept the return/exchange as the product was shipped to you after a successful quality check"
But it was already damaged
