Disabled and received a PCN from Premier Park Ltd

Junx

in April 2022, I received a PCN from Premier Park Ltd, where I parked by costco in Cardiff.  I am disabled and in getting out of my car, my badge fell onto the car-seat, passenger side.  I appealed the PCN and it was declined.  I went to POPLA and the appeal was declined.  I wrote to POPLA again and they declined my appeal again.  After that I received several Debt REcovery Plus notices and ignored those.
In MArch 2023, I received a letter before claim from Gladstones Solicitors.  I completed the form but also asked for the Equality Policy from the client, with specific reference to how they support disabled service users.  No response.
Now, just over 2 years, I receive a letter of claim from BW Legal.  This time a wrote a complaint email to Premier Park Ltd and also detailed my request for their reasonable adjustments and practice for disabled people.  I am also sending a HOLD notice to BW Legal.  
So my question is 2what else can I do".  I am very anxious about this as it is now 3 years and I am afraid it is stressing me out.  Any other advice will be appreciated, thanks

BW Legal Letter Before Claims are sometimes a bluff. I have 2 in the drawer from years ago.

You can ask for breathing space and tell BW Legal that you are vulnerable. Use those words. Show as much evidence as you can.

What happened when you complained to the retail park? That will still work now if you cite discrimination under the Equality Act 2010.
