PCN, issue number not working and incorrect reg number

mayhannah

I was issued a PCN last week in the carpark of my residence (I don't have a permit, they had no spaces left when I asked). I did break the rules for one night but I feel the fine is unfair given the circumstances (I parked to avoid walking across city on my own, female, late on a weekend evening) and I was obstructing no one given it's a holiday period and most people have gone home to families.

But this aside, I went online to pay the fee and the website kept on telling me my issue number was not on their system - still 10 days after the ticket was issued. So I rang to pay, and they told me my details written on the ticket did not match what was on their system. It was ONLY THEN I realised the issuer had not written my registration number correctly. So I told the woman I'll ring back later.

My situation now:
Pros - They have the wrong registration number on the ticket and on their system. The issue number was not working on their website (but is on the system in the office when I rang?). I did not declare my name or any personal/car info when I rang the office.
Cons - The carpark has CCTV. I also tried to appeal to my landlord rep, so they could potentially find me through my landlord/estate agent.

I'm unsure what to do next, contact the company that issued the PCN? I rang citizens advice and they said I have two options, to ignore it in the hope they won't attempt to find me in other ways (through the landlord, look at CCTV?) or just pay the fine and be done with it.

I do think I ought to contact the company and tell them it's an invalid ticket and ask to waiver it, but I'm unsure what to say? Any advice?
