I received an item that was broken because the seller did not package the fragile item as paid for

[hbunny16062011]

I bought item 131142069862 $5 for the item and $ 7.20 for postage....then after the bidding closed I notice in the account to pay the seller added 12.20 extra for packaging....i thought fair enough its a 60 year old plate.....I received the item broken because it was not even in a box.....I took the unopened item to a post office in Oakleigh and not only did they say they did not reconise the packaging as their own but they would have advised anyone to send a plate in a box (which their biggest box cost $4, which for the item would be just right) I have outlined to the seller that since they took the whole risk upon themselves not to put item in a box without consulting with me I should not have to bare any of the cost......Its obvious they do not want to reimburse my money can you help me

thanking you
