We parked my husbands car at an APCOA train station car park and paid for the 3 day ticket using my mobile phone (as I have used this system before, it was already set up).

When we returned we found a Civil Parking Notice ticket on the windsreen. At first I thought they had made a mistake, but then found that I hadn't realised that the car registration number registered with APCOA was MY car and not my husbands. I wrote and explained the problem and sent them a copy of the email confirmation I had received from APCOA.

They refused to change their decision. I wrote again saying that at no time had I defrauded them of payment, that my car had remained at home during this time, that we had paid in full for the space and time we were parked. They still refuse to budge on their decision. They now say I have to pay an £80 fine (not the £50 or whatever the original fine was) as it is over 14 days since the alleged offence.

Do I have any grounds to continue complaining? Is it worth going to a solicitor? If I DO have to pay, can I get away with paying the lower amount, the only delay has been in their time replying to my letters.
