Amazon.in — cancelled order after payment receipt on account o[censored]nable to deliver item

Address: Deoghar, Jharkhand

This time my complain is on amazon.in, I purchased a fitness item (ISO SOLID IMPORTED AB CARE PRO) on 17.04.15, while prior placing order I checked delivering location as provided in well reputated amazon.in and made payment of Rs3500/- for item. I received promise message to deliver item by 6-16days. On next day I received another mail from amazon.in regarding cancellation of my order with giving me a cause of shipping address provided was undeliverable. Now still they are showing pin code valid for deliver of same item for which I did before but after cancellation the price of product increased.
