I actually sold something on ebay one time and mailed it through the post office and didnt get a tracking number (didnt know i had to ask for one) package got lost and buyer never got it. He contacted me and i worked with him the best i could, about a month went by and still no package so he filed a dispute with paypal to get his money back. I talked with paypal and since i didnt have a tracking number to prove that i mailed it they AUTOMATICALLY take the money back, as it was linked to my bank account. Nothing i could do. I eventually got the package returned to me as i had a return address on it and there was a letter with it that said package was never picked up, so the only money i lost was shipping charges. So i would file a a dispute with paypal and ebay. You should eventually get your money back.
