Well the response is utter drivel and as they've not reoffered the discount, there's no point in paying now because even if you appeal and lose, the penalty stays the same. That being said, I think you're more likely than not to win.
Thank you. I agree - the letter also has grammatical errors and mistakes in and doesn't really address any of the points brought up throughout the process. Also as you say, I have nothing to lose from trying now as the fine is already being held at the full amount.
I know from reading through the forum it is often best to request a personal hearing rather than postal. Do you think I would be best served seeking someone more experienced to appeal on my behalf, or is this something I should do myself?
I would post any draft of the Details of Appeal cover letter section here before sending off as I have very much found the advice you and others have given helpful so far I'm this process.
Thanks again.
