Right at the beginning the second "golden rule" is 'Do not ignore letters (unless and until you have written a “cease and desist” letter)'. Yet all the way through the message is ignore all correspondance. I have sifted through a lot of posts and there seems to be a conflict of opinion. I ignored the initial unjust ticket (there were - and still are no signs as you enter the carpark). They have now bothered to look me up via DVLA and I don't know whether to reply with response number 1 or ignore them. I am happy to go with the latest opinon. Thanks all.
