How to resolve order issues with a vanished online store?

I ordered a kettle from a grindzone shop on 29th of March (order #1003) but I still did not receive my order. When I tried to report an order problems with my order the contact form requires an url from the confirmation of my order however on the confirmation email when I press view my order it says that the link is not available. When I tried to e-mail the shop it says that the e-mail does not exist. I would like to get an information on my order and receive my item or a refund. How can I get help? I tried using the chat it says to select a store however no such option is available. Moreover, I cannot find the shop on the Internet anymore.
