Looking for advice on parking ticket appeal.

Hi, hoping someone can give me some advice, and an impartial view on whether I should continue to appeal a parking ticket.

I parked in the Finsbury Park CPZ on a Sunday afternoon at 4.10pm. The restictions state that there is no parking between 8.00am and 4.30pm on 'Event and Match Days'. I know this because before setting out I had checked the Haringey Council website. The page which gave these times also said to check another page to see whether events were taking place at Finsbury Park. I did this and it clearly stated that no events were taking place. (I have kept copies of both of these webpages). I also checked the Arsenal site and no game was on.

When I arrived I also checked a Pay and Display machine, which had a different set of times, stating that you should not park before 4pm. (I also have a photo of this!!).

I contested the ticket, including the evidence given above, and today received a rejection of my appeal. The rejection states that an event was taking place in Finsbury Park (Newroz?) and that the ticket was correctly issued. (There was a sign in the road giving a premium rate phoneline to check whether events were on, but as I had previously checked online this seemed pointless).

The rejection letter makes no mention of the misleading (wrong?) information from their website, which I provided them with. It also states that I believed the parking restriction ended at 4pm, when I clearly stated that this was the information on their pay and display machine!

Obviously I have a somewhat biased view on the matter and would appreciate an impartial view based on the evidence given. Any advice from anyone else who has contested a PCN would be very much appreciated.
