I have been dealing with ebay for over 5 years. I had to sort out plenty of problems with both buying and sellers. Give the guy a break, you should wait at least 10 days before you file an 'item not recieved' claim. Usually, the seller will immediately give a full refund, once paypal gets a hold of them. Chances are he is just not checking his email, don't worry, wait a while... you'll get this sorted out.
