I received the rejection from Redbridge but can't seem to find the way to attach anymore

. So I am typing the main part where they outline the reasons:
"The signage complies with the requirements set out in the Traffic Signs Regulations and General Directions (TSRGD) 2016. Although you state that the sign was placed within a puffin crossing area, the placement has been reviewed and deemed lawful and sufficient to inform drivers of the restriction.
The prohibition applies to the entire stretch of Cranbrook Road where the signs are in effect, not solely after the point at which the sign is passed.
It remains the driver’s responsibility to look out for signage whilst driving.
We have rejected your representations because your vehicle was seen performing a prohibited turn.
You now have the following options:
Pay the outstanding amount of £80 within 14 days of the date this letter was served (the date it was delivered) after this point the full charge of £160.00 will become due.
Or you can appeal to the Environment & Traffic Adjudicators (ETA, part of London Tribunals) using the enclosed appeal form. This must be done no later than 28 days of this letter being served. An Adjudicator, who is independent of the Council, will then consider your appeal and make a final decision about whether your appeal should be allowed or rejected by the Council. Their decision is legally binding on both you and the Council."
Any thoughts?
