I can see the arguement for paypal holding funds.. but to expect the buyer to call Paypal to confirm receipt of the item is really too much. Really??  I've never heard of this before, hard to believe that paypal would release funds solely on the basis of someone else phoning - far too impractical and unreliable.  Buyers aren't even inclined to leave feedback these days.  I'd be phoning again to speak to someone else.  If you can prove lodgement that should be enough.
