Royaloak Furniture — Refund of money

I have ordered one item from royaloak website of rs9900.Then after the estimated delivery date i didn't receive the product so i called them.Then they said that i will not receive the product as it was not possible for them to deliver so the said that they will refund the amount.But till now i am not getting my refund back.Its more than 1 month now every time i call them they say the same things sometimes they even don't receive my calls and disconnect the calls.They are harassment to customers
