I didn't get my mail forwarded no, as I said I had forgotten about the letter altogether.
I did however return to my previous address a few times to collect mail but there were no relevant letters.
At the time it I lived in a shared house, and it was not unheard of for some of the house mates to sometimes dispose of the letters if they were accumulating,
also since I no longer lived there it is possible that they just threw them away.
I will get in contact with them, but having read some of these other threads,
I can't see them being very helpful or sympathetic.
Thank you for your reply!
Regarding finding out what Bylaw I was prosecuted under,
is that information they are required to give me?
I have just read that sometimes they are not very helpful when asked for certain information.
