Are you a member of the Car Club?
If so, how much is you making a fuss over this worth?
And if this is contractual as mentioned, and they are stating the terms of the agreement as I was the last renter am I still liable? [Yes, that's exactly what they're saying.] If I did not park in the correct bay I get it, highly unlikely but now I know what they are actually trying to tell me it is possible. I need to see evidence I think of when my rental ended where I was parked.[You're the one with the rental agreement, we cannot help with this].
IMO, we're not getting to the nub of this which is that you refer to bailiffs, but we haven't seen this correspondence. If your car was in contravention, what authority did you have to reverse their continuous charging mandate?
And pl clarify whether you, as an individual, were the hirer or is there an employer/company involved?
The council won't entertain any correspondence regarding this matter, so that avenue is closed IMO. So forget 'appeal' unless perhaps you could engage with an Alternative Dispute Resolution procedure, to which their ECC Ts and Cs refer:
