Hello again. The reply is in today, a rejection, in a very similar wording to the previous letter.
Unfortunately, this no longer appears to be the case:
Well the starting point is that, as long as you challenge the Notice to Owner within 14 days, the council will re-offer the discount (to discourage you from appealing to the tribunal), so you might as well carry on.
So the full £110 cost is payable now.

On the other hand this means there is nothing to lose by appealing to tribunal so this is now the obvious choice, so I would appreciate guidance please.

I can appeal online again it looks like, so the question is what I should write?
For context....
I do think the signage where I entered the zone is particularly poor. From street view, one sign is not at all visible (immediately opposite junction) and the sign on the far side of the road is partly obscured by the Give Way sign at the junction, then visible only briefly when attention is on the zebra crossing (see the signs ringed in red below). I did not see any repeater signs between here and where I parked.

Thank you for the guidance so far!
