I have received a parking charge notice from a private firm, which states that I was parked in a restricted area in Nottingham last Saturday. This is an error because neither my car nor myself were in Nottingham at the time stated -I have never been to Nottingham!

I have explained this by email and now have received an email saying that in order to appeal I must provide the driver's address. As my car wasn't there, there wasn't a driver! Shall I ignore this? And what are the implications if I do?
