Euro Car Parks

My appeal to Parking Charge notice No 88881534986 was dismissed without addressing the reason given for my appeal in their email response. I paid £4 in coins for the parking period concerned on 3rd November 2018. The email attachment they sent says I did not purchase a ticket and that I should have paid £3. The email was of the type that did not accept replies. On the day of the event the machine did not issue a ticket but I entered my full Car Reg Number into the machine and inserted four £1 coins. The car park had entry and exit cameras. I therefore took it that tickets were not issued for their system. It now seems clear that their machine was faulty if it should have issued a printed ticket. This would have been my response to their dismissal email. Having paid fully for the parking I would like the Notice to be cancelled.
