This happened to me but I was the customer. I bought a laptop, the order was confirmed through a personal reply to an email, and they satated that the payment had gone through and that the order had gone to the warehouse.
9 Days later I get an email saying I have a full refund with the reason being the same as yours "Refunded by Google 02"
I have emailed the company through google twice but have not had a reply.
Im just hoping that they have send it off already, and will arrive in the post sometime soon for free!
