@cp8759 I wrote as you suggested to appeals@ealing,and cc'd the head of parking, recieved an email from one of his staff.
This is her email to me:
"Thank you for your email.xxxxxxx has asked that I respond.
Having investigated the case I can advise you that our records show that a payment of £65 was received 30/05/2023. However due to a technical error the monies were not assigned to the case and therefore progressed to the Charge Certificate being sent.
The case has now been paid and updated accordingly. No further action is required by you."
Just like to thank you,and the others who advise selflessy on here,without asking for anything back. My faith in humanity is restored.
(But not in the effing local council)
