Free Traffic Legal Advice

We live in the middle of nowhere so our mail is a  it sketchy at the best of times. I had wondered if the first letters hadn't even been sent and they've gone straight to these last letters to stop you trying to appeal and up the fine.
Is there nothing that will just quash this without having to try an appeal? Im not sure on the reasons for the over stay, I'm just the registered owner and not the driver.

Recieved this letter to the registered keeper. The thing is we never recieved a first mail. This second was also recieved 6days after the date on the letter.
How can we kill this please?
