Welcome. There are always grounds for fighting these scams. Photos of the signage at the location, including general layout photos and also some photos of the signs in the same lighting conditions, without flash or headlights are useful evidence.
According to the date and time on the Notice to Keeper (NtK), it would have been almost dark by that time. How recently did the terms of parking change? How were these material changes in terms notified to motorists, if at all?
The GSV images are from June 2024 and there was no signage then.
