As a seller, it is your responsibility to know the user agreement T&C's, you would be subject to a 21 day hold on funds, as a new seller. As your items appear to have been pickup only, why did you not stipulate cash on pickup.
You would have been notified when payment was made via paypal, and your funds would have shown as on hold, so it was then up to you to either ship the item of provide collection details to the buyer.
