@Phaeton55 the notice to owner was issued on 30 May 2024 and is deemed served on 3 June, so to meet the statutory deadline the representations needed to be
received by the council no later than 30 June 2024. If you decided to send the representations by post on 29 June then this deadline was never going to be met: representations could and should have been made online at
https://payment.medway.gov.uk/public/Pcn/lookup (you can usually upload attachments and even if you couldn't, at least you wouldn't have lost the right to appeal to the tribunal).
The council is entitled to disregard representations received after the end of the 28 day period, so unfortunately you have no right of appeal and the only thing you can do is pay the Order for Recovery before any bailiff fees get added.
Why on Earth in 2024 people insist on sending letters by post is completely beyond me (especially considering that everything is scanned into the council computer and shredded anyway, so you might as well upload everything into the council computer yourself)
You're not the first person to shoot themselves in the foot by doing this and I fear you won't be the last.
I'm really sorry there's nothing more we can do to help you, but it's better to spell out what's what rather than giving you false hope.
The really frustrating thing is that I found out today from Kent County Council that they can't find a copy of the traffic order, so if we'd got this to the Traffic Penalty Tribunal it would have been a really easy win.
