I wonder if you can look into terms and conditions on the seller's website. Specifically in regards to accepting Paypal payments. If they don't specifically state that they only ship to paypal verified address you may have something since you put the correct address into their order form....
Sucks, i've done the same thing but luckily my old address is my rental home, so i end up getting it anyway. Good luck.
