IMO, first you need to establish the facts and provided you are the registered keeper you have the means to do so. This has nothing to do with parking regs or procedure-as posted by others these have been terminated for the present- it's just doing the obvious i.e. establishing simple communication with the authority.
No accusations, no recriminations, no 'I've got a defence' etc. just I made representations online on *** and didn't receive a Notice of Rejection. While I was out of the country or whatever on business between ** and *** my sister, who lives with me and I still love dearly, took fright when the Charge Certificate arrived and paid thinking she was doing the right thing. I am still trying to piece together why I did not receive a response to my representations and I hope you can assist me. If you did issue a NOR, I should appreciate a copy.
If you need further information from me please let me know.
Regards,
