Regardless of the feedback, if you have received the door there is nothing left to do. Had you not received the door, you could have gone back to Paypal and asked for your money back.
As it stands now, the transaction is over, you both have negative feedbacks,and you can't do anything about them.
My suggestion, is that the next time, don't be so quick to leave negative FB. Most thing work out, maybe not the way you would have liked them too, but they will will work out.
