POPLA Appeal Help

A couple of months ago we received a parking charge notice while parked at Meadowhall shopping centre. With hindsight, after reading the newbies post, and probably using common sense we should have taken a photo of where we were parked and appealed to the shopping centre management as the ticket was for "parking in a restricted area" which we weren't, we were just parked in a "standard" bay, but we didn't so this is where we are.
Approximately 6 weeks after the ticket we received the notice to keeper to which we replied and appealed using the BPA template letter on this site, the parking company, CP PLUS Ltd, is a member of the BPA.
A couple of weeks after that we received an email asking us to confirm the name and address of the driver, which we declined to do.
A couple of weeks after that we received an email saying the appeal had been rejected, which is at the bottom of this post (with some links removed to allow me to post) and providing us with a POPLA verification code.
My main question is is it too late to appeal regarding the nature of the notice, i.e. that she wasn't parked in a restricted area and is the onus on them to prove that she was, do they need to have photo evidence or should we have it.
Any advice on this and the best way to word the POPLA appeal would be gratefully received,

Thankyou.

"Thank you for your email regarding the above Parking Charge Notice (PCN).

I have carefully reviewed the case and have considered the points that you raised. Unfortunately, I cannot cancel the PCN and it is still payable. I have explained my findings in more detail below.

My findings

The site in question is subject to terms and conditions, which are stated on signs throughout the area. As these terms were breached on the date in question, a PCN was correctly and legitimately issued.

Internet templates

I must also stress that simply sending in standard template responses, most likely obtained from the internet, will not resolve the matter. In addition, I would recommend that professional legal advice be sought on this matter as an alternative.

Signage

The signage on site is sufficient and is in line with the guidelines laid down by the British Parking Association (BPA).

The majority of motorists who park at the site do so without receiving a PCN. This is undoubtedly due to the fact that they are aware of the terms and conditions of the site. If, as you claim, the signage was inadequate, the terms and conditions of the site would be unknown to the majority of drivers and many more PCNs would be issued here.

What you need to do now

You now have three options to choose from:

1) Pay the PCN at the prevailing sum of £120.00 by 08/09/2017. Payment can be made online or by phone. Go to or phone 0208 528 4122. You can find full details of how to pay on the PCN issued to the vehicle and/or on the letter(s) sent if applicable.

2) Make an appeal to POPLA (Independent Appeals Service) by appealing online at (verification code: ). The only grounds for making an appeal are stated on the website and to be considered the appeal must be received by POPLA within 28 days of the date of this correspondence. Please note that if you opt to appeal to POPLA and the appeal is unsuccessful you will be only able to settle the PCN at the full amount of £120.00.

3) If you choose to not make payment or appeal, the amount outstanding may be sought via a debt recovery company and/or court action where further costs may be incurred as a result.

More Information

By law we are also required to inform you that Ombudsman Services provides an alternative dispute resolution service that would be competent to deal with your appeal. However, we have not chosen to participate in their alternative dispute resolution service. As such, should you wish to appeal then you must do so to POPLA, as explained above."
