The PCN was affixed to the car windscreen

I think there are now signs on both sides of the road in the lower location - I could go and check but I doubt it's material, any more than the leaves obscuring the RH sign in the upper photo.
I don't dispute that I was parked where and when they said, and the evidence is very clear.
The only error I can see is that they have miss-spelt the name of the road on both the ticket and the appeal rejection as "Clovely" rather than "Clovelly".
BTW - I've not been sitting on my hands since they rejected my appeal, they posted it on 2nd November, which was a Thursday, and therefore their presumption was that it would be delivered within 2 working days, i.e. Monday 6th, which is when the 14-day countdown for the discounted payment window started. The day after it came I started a topic on Pepipoo.
It was actually delivered on Thursday 16th, 10 days late. I have asked if they would extend the 14-day window by 10 days, on the grounds that they must know that it is unsafe to assume that Royal Mail will deliver when they should, and that injustices can arise if they do just assume.
If they don't then tomorrow, Monday 20th is my deadline to either pay £55 or decide to "make further representations".
So I guess what I'd like to know is are there any "technicalities" which give me a sporting chance of getting this dismissed, or should I just pay up while it's going to cost me £55 rather than £110.
