That's strange because I ordered from them two weeks ago and I got a confirmation number and the item arrived yesterday. I doubt that the earthquake had anything to do with your situation but I guess it could be a possibility.
Did you include any active links in your e-mail? I did when I was trying to figure out the issue with my hop up chamber (turns out its was not compatible, so they are sending me a new set of gears), and they did not respond. I sent them 2 of these e-mails and no response. After I sent them one that did not include these links, they got back to me via that e-mail the next day.
