Good! Please don't communicate any further with APCOA. If/when you receive either a PCN or a fake PN through the post, show it to us, only redacting your personal info, the PCN number and your VRM. Leave everything else visible, especial all dates and times. Also check their appeals site to see what other evidential photos they have, if any.
No one pays a penny to APCOA if they follow our advice.
