Product - puma sweatshirt

First product issue-my name is avijit singh, my wife ordered a kurta of sangria brand for herself from myntra. The kurta had 2 layers, the outer layer was clean but the inner which was white in color had some old light brown stains. Kurta was too tight for my wife since the size ordered was small usually she wears medium (We ordered small since it was last piece available on myntra and was under huge discount so we wanted to give it a try if it fits). Finally it came in very bad packaging and it did not fit also so we returned. Later it got rejected in quality check stating that it's used product. And myntra has sent me back that product.
Second product issue - same as above. I received stained white puma sweatshirt with very bad pacakging. So i took picture and video of it and raised return. Today the product got picked up and failed quality check. I beleive in covid this is their tactic to make profit.
We have called multiple times to myntra customer support since 10 days and asked to escalate the matter. Everytime they assure for call back from higher authority but never received a single call.
Then we used twitter to escalate the matter then today we received call from some manager named sanjay from myntra to address the first product problem. And the resolution what he gave is "myntra quality check is awesome so he can not return money for".
Why should we pay for something which we have not done. I am sure that myntra guys are not doing quality check before sending the product to customer since several times i have received defective, damaged, badly packed, dirty, crumbled products.
This clearly indicates these guys are cheating customers by false alligations.
