I have have had 4 PCN now. After the first one the company were contacted by myself and local housing authority that the space in the Close was purchased along with the house. All the others except my neighbour, who has also had one PCN that I know of, are rented and require permits. Some time ago the Close was taken over by this parking company and they stuck their sign right between the two private spaces
. I ignored the subsequent PCN, as I thought if they contact the DVLA and get my address, they would have it on their system but no I get a Notice to Keeper letter demanding the full fine. So I go and try to find their registered address, driving round and asking people. Eventually found it but they had moved 2 years ago! Tracked them down and banged on the door. They let me in and I asked to speak to the manager, he had gone home for the day (his was the morning). I very politely asked them to stop harassing me and to move their sign. They told me to put it all in an email! 
I’ve emailed my local MP and also will write a letter to Trading Standards. Anyone else? What should I write in the email?
