Address:

560055

Hello sir,

I have placed an order sarees at price rs. 88/- as on 10 december 2017 at 12:52pm on amazon site. And i pay successfully from my amazon pay balance.
My expected delivery time is 14-15 december 2017 and i was waiting for my product for delivery. On 15 december 4:00pm i have got mail mention "this is to inform you that your order[protected] was cancelled. It's very shocking for me. I am very embarrassed how could amazon do this and cancel my order automatically without any reasons after successful place order. I am a prime customer of amazon. Cancel order after price inflation 832/- and ending of all deals/offer on competitive e-commerce site. So please deliver my order otherwise reimbursement inflation price
Immediately.

I am valuable prime customer of amazon at and purchase more than 30000/- in a year from amazon i am not expecting this type of cheatings and service
