Myntra.com — Product returned without attempting delivery

I have purchased a jacket under Deewali Promotional offers. It was placed successful and tracking shows that it reached my nearest delivery hub, but all of sudden it was cancelled and being returned to myntra. Upon talking to customer care they said because of operation issues it is being returned, please purchase again with new price.
Price has increased by more than 5000. I want to know if you are cancelling without informing the customer is not a good practice and this has happened multiple times and sale has became a joke for you.
