I have set out the legal process.
Forget everything prior to TEC's revocation order.
If you have not been provided with a PCN at any stage then the ball is now in the council's court. The process starts again. You will have a chance to put your argument to the council AFTER you receive the new PCN and not before.
The council have until 3 October to serve the new PCN.
So pl stop chasing them, at this stage it's counter-productive. If they fail to serve a PCN by 3 Oct. then you win by default, so why would you want to jog their memory?
