Good afternoon all
Thank you for providing this forum and your help.
I have received this PCN from parking in a pay by phone space. I arrived at the space just after 5pm. In line with my resident status, I am entitled to 30 minutes free on Ringgo. I thought I had booked this and was surprised to get a PCN, but have found that it must not have gone through; signal is notoriously bad on this street and it often takes multiple attempts to get the app to load. I thought I had managed this time but clearly not.
Had this gone through successfully, this would have taken me past 5:30pm, at which point I am entitled to park for free (1 hour before the parking restrictions end). I would therefore have paid nothing for the entire stay.
Is there any point appealing?
Thank you for any help.
