Amazon India — my confirm order no[protected] cancelled even after online payment

Paschim Medinipur, West Bengal, 721101

Dear sir,
My confirm order no[protected] cancelled even after several time confirmation over telephone also. I made payment of rs 41998/- the hold the money for a week, then send me a email that the order is cancelled due to pricing error by the saler. This is malpractice by the saler. I do not know that some one return money after salinng process is completed. This is not fair. I also phoned to your officer that why my product is delaying? They verbally guaranteed me that i will receive the product within decleared time.
But unfortunately today i received the cancellation massage. This is very sad and irritating me.
I again request you to send the product at my purchased value.

Thank you. Dr swasti pada chatterjee
