Parking Charge Notice PARKING EYE

Hi

I'm wondering if anyone can advise me on a Parking Eye charge I recieved.

I was parked in a car park waiting for my daughter to come out of the train station in Leeds .The car park was very dark and very few cars parked there ,i didn't realise I had to pay to sit in the car park !!!I was sat there for 24 mins according to this parking eye company.They have my car photos and reg , time of arrival and departure. I tried to appeal but they have rejected it, shall I pay £60 now or send a letter to POPLA and risk another rejection and a larger fine of £100???

Please advise

Thanks
