Could I suggest an alternative?
If all we're looking to do is to speed along the council's actions, then IMO any communication should be restricted to this point and not veer into whether the contravention occurred or not.
Dear Sir,
PCN *******; VRM ********; Issue date *******
I refer to the above, your letter dated 8 June 2023 in which you stated that my formal representations were (oddly) rejected on 30 March 2023, your Enforcement Notice dated 5 May, your CC dated 26 June 2023 and today's date of ******.
A period of over 7 months has now elapsed since the CC was issued.
As owner, I am entitled to expect the council to expedite matters in a timely fashion and not to have to order my life so that I would be on hand to submit an in-time Statutory Declaration to the Traffic Enforcement Centre should the authority belatedly decide to issue an Order for Recovery.
Within the next 2 weeks you should either
Issue an OfR, or
Cancel the PCN.
Yours
