You parked on 13th;
A warning sign was erected, by implication exactly where you were, 6 days earlier on 7th;
You are a permit holder and yet somehow you didn't notice this sign in the following week;
You were parked immediately next to the suspension sign; the council's duty is not to compose diagrams with 8-figure grid references to convey a suspended area but to provide 'Adequate information.....as the order making authority may consider requisite'.
IMO, if you took your point regarding the plan to adjudication it could be considered as bordering on frivolous.

"The PCN remains enforced however we have extended the discount period for a further 14 days, giving you the opportunity to pay the discounted amount which will be accepted as full and final payment for this PCN.”

When would you calculate the newly extended discount period to end?
