After reading further seems to be same topic as listed by The Great Soprendo and squirlyline.

Good Morning, I have recently received a Parking Charge Notice by CPM UK Car Park Management for a short stop on Trinity Park Roadways, Birmingham. I pulled over for about 15 mins, While I was there I took a phone call. I didn't notice any signs saying I couldn't pull over and stop and I didn't ever leave the car. Any advice would be welcome. Should I respond ' without prejudice' saying I am refusing to pay?? 1 Date of the infringement 6/10/19 2 Date on the NTK [this must have been received within 14 days from the 'offence' date] 10/10/19 3 Date received 14/10/19 4 Does the NTK mention schedule 4 of The Protections of Freedoms Act 2012? [Y/N?] Y 5 Is there any photographic evidence of the event? Y 6 Have you appealed? [Y/N?] post up your appeal] N Have you had a response? [Y/N?] post it up N/A 7 Who is the parking company?

Good Morning, I have also in the post just received a PCN for the same area - Trinity Park Roadways. With two photos 16.15 & 16.16 time stamp with an incident time of 16.20. I was only in the area for a short time, pull over didnt notice any of the signs due to the size of them. Several other cars, inc a couple of taxis sitting around same area. Can I ask has your charge progressed any further?
