Effectively the auto-pay sign-up is similar as you provide a number plate but don't specify a date but agree to it to auto charge you for any visit registered.
I think I am covered as I have signed up with their system for auto-pay and they are failing to take the money, so if they were to come after me there would be clear evidence that I have done what is required and it's their fault they didn't take the money, but these parking companies are a law unto themselves.
'I'll see you in court' if they misbehave. Sounds like you took all reasonable measures to pay the fee, don't tell them anything, let them find it out themselves and ask for the money.
