What you have uploaded is a letter with daft empty threats from third-party paper tigers.  Just ignore it. What we need to see is the original invoice you received last October or November.

Thanks for posting the CPR contents. i do wish you hadn't blanked out the dates and times since at times they can be relevant . Can you please repost including times and dates. They say that they sent a copy of  the original  PCN that they sent to the Hirer  along with your hire agreement documents. Did you receive them and if so can you please upload the original PCN without erasing dates and times. If they did include  all the paperwork they said, then that PCN is pretty near compliant except for their error with the discount time. In the Act it isn't actually specified but to offer a discount for 14 days from the OFFENCE is a joke. the offence occurred probably a couple of months prior to you receiving your Notice to Hirer.  Also the words in parentheses n the Act have been missed off. Section 14 [5][c] (c)warn the hirer that if, after the period of 21 days beginning with the day after that on which the notice to hirer is given, the amount of unpaid parking charges referred to in the notice to keeper under paragraph 8(2)(f) or 9(2)(f) (as the case may be) has not been paid in full, the creditor will (if any applicable requirements are met) have the right to recover from the hirer so much of that amount as remains unpaid; Though it states "if any applicable ...." as opposed to "if all applicable......" in Section 8 or 9. Maybe the Site could explain what the difference between the two terms mean if there is a difference. Also on your claim form they keeper referring to you as the driver or the keeper.  You are the Hirer and only the Hirer is responsible for the charge EVEN IF THEY WEREN'T THE DRIVER. So they cannot pursue the driver and nowhere in the Hirer section of the Act is the hirer ever named as the keeper so NPC are pursuing the wrong person.  

This is simply a scam site.  It's been shown to be a scam in the national press and on national TV. Please fill in the the forum sticky and upload the invoice you've received. In fact what you have is an invoice, not a fine, a private company doesn't have the power to issue fines.
