Free Traffic Legal Advice

I received a letter through the post from TfL, which appears to me that they will be proceeding with its enforcement and taking me to London Tribunal.

The envelope included an evidence pack with about 50 pages on the case. All this despite the County Court ordering TfL to revoke the Charge Certificate.

One thing I wanted to note, is that under the ticket history TfL provide in the evidence pack, they say that they emailed me with a response to my challenge on 5th Feb… I’ve looked through my emails and can find no email from TfL on this. The whole reason I’m in this position is because I didn’t receive a notice of rejection to my original appeal, otherwise I would have paid the discount amount.

How do I proceed from here?

I’m a bit confused, I logged in to the TfL portal to see what it says, and it’s now saying £160 due, which is the full priced PCN.

I’m not saying the contravention did not occur, I don’t think I can argue that. But what I can argue is that I did not receive their response and therefore should be given the chance to pay the discounted price, but I know losing at the tribunal  would mean I’d have to pay the £160 anyways… so what can I argue?
