Myntra.com — My product is not delivered yet but they marked product as delivered on app

I have ordered a lipstick and moisturizer which is not delivered yet and they marked as delivered on app I raise an issue they marked as resolved without my permission even though issue is not resolved by my side I didn't even receive a call or message by delivery partner or myntra regarding delivery I reopen my issue but they are not taking complaints now they are saying it's been longtime since you have ordered infact they are the one who takes almost month to resolving my query and it's still not resolved.
