Myntra.com — myntra claims my undelivered package as delivered

Address: Belgaum, Karnataka, 590006

Website: Myntra

I had ordered a kurti and a sweatshirt from Myntra, I wasn't home to receive the order then I received a message saying the package was delivered which in fact wasn't delivered to any of my family members or my friends. When I contacted Mantra customer care about this they sent me a sign to verify, which I called them up after 7 days saying it wasn't recognizable they claimed they cannot do anything about it.
