If you are up for the fight, (i.e. not hiding from the mrs), they will have to provide some evidence. Was it a pay & display, if you were displaying they couldn't produce photographic evidence that you weren't.
Just sayin'
Just a little help for you BOD has ive worked in this sort of field before and i asked a friend today for you who still works in this area of work if you are Perfectly happy to recieve 2 - 3 more letters from the company over the next 1 - 2 months then do has follows when you receive your second letter send a letter or email back stating you entered the car park at the time you did paid at the machine and time you left the car park Also putting at the bottom you have spoken to a legal team has you believe you feel this is a scam and they have first instructed you that if i receive any more i shall go to the local council
This will proberly get a letter sent out saying due to the situation we will half the cost of the fine if you pay within 7 days (do not )
simply send another letter or email saying you will contact the council this will proberly nnow put the situation to bed and they will send a letter saying good will gesture they will cancel the fine
This will show its another hardcore waste land car park to avoid i know of 8 around birmingham
Now if they are above board and they do not have a camera somewhere in the carpark filming on the carpark machine so they cant prove you have paid or not then ask for proof of a picture of you car parked with no ticket on your dashboard or stuck to the car window ( now there is a clause in the window they have the right that the ticket and it does say must be displayed on the drivers window or dash board or drivers side of the front windscreen putting the ticket on the passage side window can still get you fined even if you paid )
If they can not come up with any pictures of your car with no ticket in or you walking from your car and avoiding the machine they really have no proof and the court will not accept this the court can ask the car park company to audit there machine has for example say on the day you parked only 10 cars came in that means the car park machine would have printed 10 tickets
The last thing iam not to sure on the car park you went to but you say it got a picture of your car number plate was in a barrier car park which lets you in then you go to the machine pay your money say 1 hour then on return go through a barrier to exit there are some places where you have to enter your ticket back in the barrier has you exit if you dont know this and tail gate some one out the car park because the barrier is still up it then the barrier computer which records the number plates come in and out still thinks you have not paid because its not received your card so in which case again an be sorted by the ticket machine taken more more then what has been processed
the ones to watch out for are the ones in supermarkets
