www.lovbuy.com review: I haven't received the refund, but the seller promised to return it a long time ago 2

I searched for the laptop on the website www.lovbuy.com. I found one laptop and ordered it. After that I got the email from the seller, and it turned out that the laptop was unavailable. I asked to return money then, but I have waited for 3 weeks already and still got nothing from them. I wonder if there are people, who faced the same problem? I really need help or any useful advice. Please, post your comments and ideas. Thanks.
