Hello,   my wife today (23.04.21) received a PCN from CP Plus.   She is an NHS employee working at the hospital for the past 20 years. There is no reminder and the parking badge that she pays for ran out at the end of March and there is no system that reminds her.   The PCN is for £ 80 or £ 40 if paid with 14 days.   Is there a defence that can be used or just bad luck?   Any help appreciated.
