parking charge to wrong address

I had a parking charge two years, I appealed but heard nothing back. It now transpires meters have been going to not my last address, it the address before which I moved out of in 2013.
They sent the first letter to the house I was in but then anything after that, to my previous address?!
This letter is now talking about court action, and the fine it’s £160.
Can I challenge this further? Do I ignore it?

Thanks
