Amazon India — payment not refunded although they cancelled the order

Website:

www.amazon.com

My order #[protected] for a shoe rack has been cancelled by amazon although they took payment through debit card.
They said that they refund the money in my account but still now they haven't.
They also removed that order from my order section and i am not able to contact them reguarding this
They did a fraud by cheating.
Don't know why a company like amazon is doing this type of cheating.
Earlier they returned my order of a book by saying door closed but they didnt even contacted me.
Cheater amazon, return my money or i will go to court.
