The ticket was sent by Parking eye car park maangement.

Could anyone please help me? I live in England and was in Scotland on 24th August 2011. I was visiting Bathgate retail park and have been issued a parking ticket from them. They have sent me pictures of my car entering the car park at11.19am and leaving at 14.14. They say the car park only allows 2 hours parking. I do not recall seeing any signs when I drove into this car park. If anyone lives in this area or knows this retail car park, could they please let me know if they do have adequate signs posted. I really can't afford a £50 parking fine.
