It is clearly the seller's obligation to put the sold object into the buyer's hands and the buyer's obligation to put the payment for received goods into the hands of the seller.
It is unfortunate that this occurred, but it could have been avoided if the buyer had used a form of payment that could be replaced such as a check, money order or PayPal .
If the Seller has waited a year for payment, he or she has been more than patient.
