If the drivers identity has been blabbed, inadvertently or otherwise, that just means that a PCN that could have been cancelled with one single appeal will not be a protracted affair with the Keeper receiving endless debt recovery letters. Not that debt collector letters should be responded to because they are powerless to do anything except to try and persuade the low-hanging fruit on the gullible tree to pay up out of ignorance and fear.
Sadly, most of the low-hanging fruit don't understand this and end up paying something that they didn't have to pay at all. If the OP does nothing whatsoever from now on, this will all fade away eventually as APCOA are not litigious.
