Still no reply from them; been 6wks. I gather they'll be very very busy with ULEZ PCN's going out left right and centre starting today.
I was re-reading the enforcement letter and I noticed it said that my address needs to be included on the response.
As I made my response online, I didn't include my address on the PDF I uploaded (on the basis that it's not mandatory to even upload a PDF, and a response/representation can be made by responding into the text box on the website directly.
I opted for a PDF as I would have hit the char-limit.
Anyway, just wondering if they'd be super anal about it and throw out my representation on the basis that it didn't have my address on it - seems unlikely considering the overall response will be tied to my address and name, as it's all linked to the PCN charge #, and when responding without any attachments you're simply required to type into a free text box.
