Royal Oak didn't deliver the product but charged the amount

I ordered two items on August 9, protected in online www.royaloakindia.com website. I have been given the reference number ROYprotected for my order and later I got two messages to my cell number (+protected) that my order is confirmed and here are the order number: protected. They supposed to deliver the items by August protected, protected but it is not delivered so far. I followed up with RoyalOak customer care several times but it is not moving. I requested them to cancel the order and refund my money, they responded to refund my money 3 months ago but it is not happening so far. Please check with Royal Oak and help me getting my money back. Thank you so much.
