You've blanked out too much. We need to see PCN Number and car reg, so we can view the video, which is the sole evidence.
There is also a technical appeal available if you take them to London Tribunals, but I'll let Hippocrates explain it. As this is Havering, they will not re-offer the discount if you submit reps, so it's either pay-up, or take them all the way to London Tribunals, because the penalty remains the same.
