On 31/1/24 I signed up with the Greater Anglia - NCP station parking portal ready for a trip to London on 9/2/24 giving them my car and credit card details and received an email acknowledgement. I used the car park at Manningtree station on 9/2/24 expecting to receive a 12 pound bill through my credit card. On 8/5/24 I received a letter in the post demanding a 100 pound Penalty Charge Notice. The letter was dated 19/4/24, so the 14 days reduced charge period was already exceeded before I received it???? I went online to the portal and there were no outstanding charges showing, so the automatic payment system didn't work. I appealed using their system and they reduced the PCN to 20 pounds, but I still feel aggreaved that they have never billed me or issued a reminder, just straight to PCN. If they can acknowledge me automatically by email, why couldn't they send a reminder? Clearly their system has failed.... why should I have to pay for their incompetence.... I have leant my lesson, I shall avoid NCP car parks in future... their loss.
