Myntra rejected my return by stating that quality check does not passed.

I ordered shoes for my mother-in-law Kumud Gupta on 15 June 2023 and it got delivered on 16June 2023 .
In just matter of 30 minutes the return request was raised due to size issues .
The shoes was picked up on 17June 2023 in original packaging conditions. The person who picked up checked the tags and everything and did not complain about anything . In evening i recieved mail that returs in on hold and then after in 3 mins that the return request in declined without stating any details about it .
If the product is returned in the original condition of delivery then the return should be successful . I am trying to reach them but there is no reply on my chats.
