Myntra.com — Product marked delivered without delivery

ORDER ID 123808821645500013501
My product Allen Solly men blue printed slim fit shots has not been delivered but it is showing delivered on app.
I have lodged complaint 4 times through help centre but every time they close the incident stating that the logistic team has confirmed that the product has been delivered. Do they have any proof? No but they do have call records of the delivery agent which they can get.
I have also tried reaching customer care executive but they always hang up the call without resolving the issue.
It’s really pathetic seeing how Myntra is taking care of the grievances. It’s not expected from top fashion brand.
