It will be a life learning experience for you. Can you show us one of the Notices ti Keeper (NtK) redacting only your personal details, the PCN number and your VRM. We need to see all dates and times and the location information.
Also, can you show us exactly what you put in your appeal to ECP. Once we've seen that, we can put together a POPLA appeal where this should be cancelled.
Even if POPLA do not accept an appeal (they are beholden to their paymasters, the very companies they are adjudicating on) it means nothing and this will lead to a county court claim where, I can claim with 99% certainty, the case will wither be struck out or discontinued. Even if you were a 1 percent that made it all the way to a hearing, it would win.
