I advise you tell them you've never had anything from BPM and tell the DCA to refer it back to BPM.
Don't worry about the debt register or whatever, you can't go on there (if it exists?) unless:
They take you to court
You somehow fail to win (which won't happen because if you get taken to court you will come on here again, and also go to pepipoo.com and let us know, whereupon you will be bestowed with legal advice for everything you need to do)
You then do not pay the money as instructed by the court, only then can a CCJ be issued.
Don't worry! Remember, it would be up to THEM to prove their signs were correct when you parked, and even then, £345 IN NO WAY WHATSOEVER represents their losses for you having overstayed!!!
