I have requested the traffic management order, so you don't have to worry about that.
I see the discount is still available on the council website, so it might be an idea to just put a basic representation in just saying the contravention did not occur, in the hope that the discount will be re-offered. You can assume the council will reject anything you say, but if you make representations during the discount period, they will normally re-offer it in the rejection in the hope that you won't appeal.
Before you have to decide whether to accept their kind settlement offer or appeal to the tribunal, we should have the traffic order back.
