vehicle was owned by me/my company. Date of that notice was 26/02/2025.
'Me/my company' are not synonymous. Is the NTO addressed to you by name or to a company by name? Even if your name appears as part of a business title, it's a company, not personal. These are important issues.
Anyway, as the NTO has been found and it appears not actioned then, having read the procedure, on what grounds do you think you could submit a WS?
