Refunding of money

Location/place: India

Name of company/service: Govt

I recently ordered one book from www.buymeabook.com on the 13th June, 2012 and also made an online payment of Rs.437/-. But later the said website send me a mail saying that the product is not there anymore and they will refund my money. But till today the 21st June, 2012 I have not receive my money back. On calling the said website, they said that they have refund it since the 15th June, 2012. So I told them that they might have done or not done so but, I have not receive my money back.
Therefore I would request you deeply to please look into the matter.
