It's probably been cloned. First report this to the police BEFORE you challenge the ticket.
What has probably happened is some chav has nicked a car of the same make and colour to yours, and they have put your plates on it so it does not trigger the ANPR

It's on a road that is covered in cameras, signs all over the place telling you that you will be nicked, and yet still some spastics do 40 in a 30 zone. You can't help some folk.
