Hi all - this doesn't seem to be a common problem, so any advice would be appreciated.   The first I knew of a parking notice (PCN) was a threatening letter from Debt Recovery Plus.  It implies they are a debt collector, but they are simply used by Parking Eye to leverage muscle and try to frighten people.   I never got any letter from ParkingEye: not the initial PCN, nor a Keeper Liability Notice, nor a Final reminder. Nope! Straight to DR+
