Fair enough - the downside of not having photos of the signage means we're not able to take a proper look at them and see what they do or do not offer. If the signage by the charging stations offers you a contract which, as well as providing charge, implicitly gives you permission to park next to the charger, then you could seek to argue that any contract is with the charging company, not the parking company. I realise the charging company have declined to intervene in regards to the parking charge, but perhaps see if they can send you a copy of the content of the signage, as it's obviously much harder to make arguments about its contents without seeing it.
- On the second, I left the (pre-populated) fields as they were, with LEX's name but I did enter my email so that the reply came to me. Therefore the second reply was addressed to LEX but emailed to me.
Have LEX given you permission to submit an appeal in their name on their behalf? And what did you put in this appeal?
Am I right in thinking right now that CE has not actually sent me anything, so I could safely sit on my hands?
Unless you decide to pay, there are risks inherent in every option, so there's no "safe" option as such. And figuring out what will happen next is rather difficult given that the parking company have somehow allowed two appeals to be submitted, and have responded to both.
They may continue to pursue LEX, or, they may decide that the evidence they have shows that you are the driver, and pursue you in that capacity. If they go after LEX, LEX may choose to pay it and try to recover the money from you - this doesn't mean you would owe them the money, that would depend on the terms of your lease agreement. If that happened and you didn't want to pay LEX, Civil Enforcement would no longer be part of the equation, it would be a dispute solely between you and LEX.
