Myntra.com — cancellation of my order without any prior information

Address:	Gurgaon, Haryana
Website:	Myntra.com

I placed an order on 23/06/2018 of around Rs3000/- during the sale. M y order contained 6 items in total, out of which I got 5 items till 2/06/2018. The remaining 1 product which was a roadster men shirt which was of Rs. 629.81 on sale but costed me Rs566 bcoz I paid by Phone pe was not even shipped from their logistics till 3/07/2018. And today it showed me that my order is cancelled without giving be the reason of the occurrence. They have forwarded the payment to occur back to my phone pe wallet in another 9 working days which is actuall Rs533 . I don't know where my Rs 33/- are gone. I am very disappointed by this behaviour. If you didn't had that shirt in stock then why did you confirmed the order. I had to gift that shirt to my brother but I am very very disheartened by this random cancellation.
