Myntra.com — Myntra automatically cancelled my orders from their end without my permission

Hey Team,

I wanted to raise a complaint against Myntra team as they have cancelled my 5 orders from their end. It was 4 Levi's jeans and 1 Levi's t-shirt.
I have been talking to the customer care of Myntra and they're just saying it's because of their technical glitch and making fool of customers.
I want the same product for same price but they have given the me 300 points instead of order value of approx Rs. 10000.

I want to put up a complaint against the Myntra, either need all the products I've ordered or the total product amount.
