Thanks for posting up the PCNs etc.
Could you please advise us of the date that the first PCN was sent to you after the windscreen ticket.
That has to be sent within certain times.
The charge is that you failed to clearly show your permit.
Does that mean that you had a permit but it was upside down or fallen on the floor of the car for example?
If you have a photo of the sign at the entrance to the car Park-if yes, could you please post it up for us.
I am surprised that they have been stupid enough to send a letter of claim under the circumstances but perhaps they are hoping you will pay up rather than go to Court.
One of EB's snotty letters may confirm to them not to waste any more money on you.
Don't touch them owe me £500 since January 2019 make excuse after excuse. Seem they always have software problems sending money out. Keep saying they will call back or email nothing been chasing it now for 6 mths the phone staff always have the same banter we will chase it up and get back to you then nothing!
