Seller says they are not responsible for missing item.

[justfabrics58marion]

Hello, I have read many time on these boards that :

It is against ebay policy to state in your listing : "we can't be held responsible for items lost, stolen or damaged in the post."

I agree, but where can I find proof that it is indeed against ebay policy. 

I have searched high and low for it, does anyone have a direct link?

I have a seller who says she won't refund and can't be held responsible for an item that has not turned up.

It has been 3 weeks. From WA to NSW.

I was happy to wait a while longer but think I may need to put in a claim, she sent items in an envelope and says it is my fault for not purchacing tracking.

As a seller I take responsibility for missing items that I send in an envelope, and refund if they go missing.

But just incase she asks for proof about not being able to put the above terms in her listing, I would appreciate any help on where I could find such information.
