Myntra.com — Two products not delivered by Myntra

I placed an order for 7 different products from Myntra on October 16, 2020. All the 7 products cost me Rs 6791. The payment was made online. I received 2 of the products on 2 different days. The remaining 5 products were to be delivered on October 22. But on October 22, I received a packet containing only 3 out of the 5 remaining products. The packet contained a bill of all the 5 products but products were just 3. The app also shows the delivery of all the 5 products. The 2 missing products are worth Rs 1918. The company says it has delivered but I have not received all the products. The company had sent the 3 products in a paper bag which can easily be torn and then sealed again by anyone. I want a refund or the company should send me the products.
