Sorry for the late reply Linda, I'd read your post on my mobile this afternoon, so it didn't flag a new post when I logged on tonight.
I once parked behind the town hall, 80p? for half hour, it was before they made the changes.
Put my reg No in, got back to my taxi, then realised I was driving a different taxi that day, numptee,

I went back to the machine and bought another ticket !!
It's a very easy mistake to make. One miss-typed number shouldn't result in a ticket.
If you want a character reference to back your appeal up, let me know
