Free Traffic Legal Advice

Just to update as a bit of context about the image describing the location;
The area is poorly lit at night, particularly on a wintery/foggy day. You can barely see the signage.
While yes, at my fault I did not change my address, I regularly visit this address. I would've easily picked up on a notice.

In fact, I would've happily paid the £60 to just avoid the drama, but now they claim they sent me a PCN prior (I did not receive one) I am now being sent the standard DO NOT IGNORE this NOTICE.
I have emailed them to confirm how many PCN's were actually issued.

The trouble is, the JD GYM Sign sits at this car park and I see gym users regularly parking here. More importantly, the JD Gym does not make anyone aware of where to park. It is purely set up to rake in money.
As they have not identified the driver, I am tempted to transfer liability who is outside of the country and let them mail letters across the english channel.

I would have happily abided by parking rules if it wasn't misleading as shown in the image above.

Please let me know on thoughts and going forward.

Appreciate all the help and support!

Good Evening Everyone,

Im making this post as I have received a PCN from Euro Parking Services at the JD Gym/Jardines in Milton Keynes.
The Trouble is, I recently moved address and basically It's all been going to my parents and my father is disabled. Effectively, I was unaware I was even getting PCN's from this private car park Operator.

I received one PCN, which I unsuccessfully appealed, I tried to contact the Landlord with no avail and I was prepared to pay £60 just to not deal with the hassle.
Later on this week, I went to my parents placed to find a letter from these thieves that apparently they had previously issued me a PCN from 2 months ago and I didn't pay, no correspondence in the post or anything!!

So now I am fuming, I have (to my awareness anyway) Two PCN from these thieves.
I refuse to pay now and want to know what my rights are as I have already unsuccessfully appealed with EPS.
They have some of the worst reviews out there and are known for being very scammy. In fact, when you try to pay their fee, it doesn't even allow you which I recorded on my phone.

I am aware that appealing with the IAS is useless. My main argument or the terms of my argument shall I say is that they claim I 'parked on their premises without entering registration on kiosk' there is no kiosk in the GYM and I have written proof from Jardines that their kiosk they use for these spots is only open until 6PM. All of these fines were issued past 6PM, So basically how can I even enter my registration if their kiosk is closed?

If anyone can offer any advice/suggestions going forward, I would greatly appreciate it. I may add, I have changed address but can't seem to find a formal way of informing them of my new address.
