Myntra.com — Delivered a substandard product

Dear sir
I have ordered a " cotton rich soft padded non wired multiway t-shirt bra" from e- commerce site Myntra.com with order no 120838877177484065401 and it was delivered on 02 July 22. On the same day I placed the return request on being recieved a substandard product and same is not executed till 11 July 22. In this regard I also logded a query through "contact us" with issue no IN[protected] on 06 July 22 and without resolving the issue they have closed the query request and also return also closed. I have confirmed through customer care that your request has been declined and rejected and there was no reason mentioned by customer care. however i have received messages on pickup fail which actually not attempted by them. Customer care said that again raise a new return request for the same but this time while applying return request, the return rate reduced near to one-third. Sir it is the grave violations of consumer rights. Pls do the need ful sir
