If you have sold an item as buyer collects, Ebay will supply your buyer with a collection code.
They give you the code to confirm collection and then Ebay will release your funds.
They do not release payment to private sellers any more until delivery or collection have been confirmed.
You should no longer expect Ebay to release your payment until your buyer has the goods.

"There are two ways to be fooled. One is to believe what isn't true; the other is to refuse to believe what is true.”
Søren Kierkegaard, Danish philosopher (1813 - 1855)
