I know how you feel. I had a buyer that e-mailed me really rudely acted like I owed him a discount because I said that I would be shipping to a confirmed with signature required in the auction and he was upset that he could not be home to sign for it. Then he got mad because I wouldn't send it to his unconfirmed work address after I shipped it.
I just don't understand some of these people... why bid if you don't read and want to abide by auction terms (especially those terms that Ebay/Paypal dictate on sellers).
Thanks. I had to vent too...
