Someone here who has any experience with the guy? Bought a couple of items from him, which I haven't received, and he's not helpful at all in the matter; he's not answering any of my questions and replies to my e-mails with like 'auto-reply' messages; "I shiped out the your item on 6/4" and so on. He provided me with a customs number, but when I try to track in on USPS it only says: "The U.S. Postal Service was electronically notified by the shipper on June 4, 2009 to expect your package for mailing. This does not indicate receipt by the USPS or the actual mailing date. Delivery status information will be provided if / when available. Information, if available, is updated periodically throughout the day. Please check again later." Does that mean that the item hasn't been shipped or what? Would be greatful for any help in the matter.
