Myntra.com — Order being cancelled automatically by them and are not getting delivered by delivery agent..they dont even contact for the same

At first, my order was automatically cancelled by myntra itself.. and the other orders were not being delivered by the delivery agent. They either do miss call and then call does not get connected.. for one order I got call but then the call was not able to connect. So, at the end I was ultimately had to cancel the order myself.. now also due ton fail delivery, orders are being cancelled by them only.. So please I request you to look into issue..I will really be thankful to you..
