Myntra.com — do not get product and charged for that.

I have bought a cargo product from them of 32 size (Order no:[protected] 8043903) but they sent a cargo of 34 size then i had returned the product and asked for acknowledgement receipt from their pickup boy but he declined to give the same and they are saying they haven't receive such product i their warehouse.
When i had take a follow up they say they haven't receive the cargo in their warehouse. Neither got back the product not the refund.
Guys they are fraudster looting the money from their own customers don't buy anything from them.
Shame on you myntra
