Go through the ropes with google checkout team. I got an email today from the google checkout staff that a refund has been issued. THANK GOD!!! I never once got a real live person from afterchristmasusa.
I notified google of my situation through this and got a response from a google rep a few days later. Give them your order number and tell them what happened.
