True, but how can any of that be proved? There is no error from DVLA that I am aware of. The information I have from DVLA says I was registered on 1.5.24 and the information I have from the police is that they checked the database on 3.5.24.
The police will have a record of what was returned on the PNC when they searched your registration number. Unless that was your details as the RK, they could not have sent an NIP to you. If it was someone else’s details, they would have sent an NIP to them. Odds are there was no trace.
