I could not find a N1SDT county court claim in the posts above. You say you have “a notice for a CCJ”. What’s this?
Parking companies routinely deny valid appeals, so don’t take this too personally.
If you do have a county court claim which I missed, please note its deadlines carefully.
If not, you’re probably waiting for a Letter of Claim from DCB Legal, to which you will need to send a response. There is then a court claim, and DCB Legal usually discontinues these claims eventually if they are defended.
Your defence looks like non-compliance with PoFA 2012 and the driver has not been identified. Will you please post a clearer copy of the original PCN, with all dates showing as well?
