The NTO is dated 7th.June, date of service 9th June, 28th day beginning with date of service is (by my reckining - open to correction) TODAY, 6th July.
THis means you must make some sort of representation by midnight TODAY.
Check the status of the PCN on TfL's website, and post up here any TfL picture(s) (is your photo a TfL picture?)
There are some cases where CEO enforcement of parking on red routes has been judged irregular - wait for the experts here to chip in.
While waiting, please post up rest of the NtO and re-instate or supply PCN no. and Reg Mark.
Also post a GSV link to the location.
