What's up with all the lousy sellers on ebay?

Bid on an item with a description of Brand new IN box
Recieved item broken, vaccum nipple missing, clearly not BNIB
Contacted seller who told him to Fuck off
Ordered 30 dollar plastic nipple from Synapse which took a week to get to him
Left bad feedback on seller page
Ebay removed it

Ebay went so shit the minute paypal bought it.

I have no problem buying from a seller with very few feedback scores so long as they are good, but if its an item thats important, i need timely and need it to be right. I only use trusted sellers with lots of positive feedback
