Myntra.com — Shirt missing in received package

Address:

Bangalore, India

We ordered two tshirts from myntra on 19th June. Received the product packet on 6th July.
The order delivery status said both tshirts are in the packet. Keeping in line with precautionary methods, we opened the package after a week and found one tshirt is missing. Myntra refused to register a complaint. After many follow-ups they said we will investigate.
After 2 weeks of investigation, they have come back saying their quality in everything was fine and our claim has been declined.
On looking at their Twitter account, all I can see in past 2-3 months are similar complaints.
It is quite evident that myntra is running a scam during this COVID crisis and trying to make extra money from its customers by sending missing products, not processing returns, closing customer complaints on their app without any reply or resolution.
They ignore the complaints on Twitter with usual replies and have not provided a solution to date.

Request you to kindly look into this matter.
