I was sent a PCN dated 15/02/2023 for Church Street Kings Lynn car park. I visited my dentist close by on 27th February 2023. Having paid by my Master card and a receipt from the pay and display machine all evidence was to hand so, today 33 days of concern later I'm now vindicated. I suggest NCP spend more time/money getting their pay machines working efficiently. Thankfully as a 73 year old my faculties are still very much on the ball, many others may not be.
