Royaloak Furniture — product not delivered and no refund

Website:

www.royaloakindia.com

I had ordered a dining table online at royaloakindia.com on 20th june 2020. The order number is roy00446404.
They had mentioned that it will be delivered on 25th june 2020, but till now there is no response from any of them nor there is any status update.
Had called customer care many times and wrote mails to customer care. But there is no use.
If the product cannot be delivered, we would want a refund of the amount.
