FILE YOUR COMPLAINTS NOW.. The refund process is easy if the seller isn't pulling a scam like this one is.. He not only was selling lights but many other commodity items.. Like posted above, he most likely has closed his Credit Card and Bank Accounts associated with his ebay/paypal accounts.. This makes getting the money back more complicated because normally when a dispute is filed the money is held from the associated paypal / checking or Credit Card account until the dispute is resolved.. If he has closed all of these, most likely he has, it makes things more difficult to process..
One thing ebay hates to do is to pony up $$$
