New ESA50 forms despite Tribunal decision. Why??

I need advice about how to proceed - I have been sent an ESA50 to complete out of the blue.

I have been in the Support Group for ESA (having been previously on Incapacity Benefit for many years) since 2012 since an Appeal Tribunal found in my favour and clearly stated on the decision notice that the Tribunal advised the DWP "never to reassess the appellant". I have a progressive, degenerative spinal condition and (no surprise) 7 years later, I am worse.

I have tried to call Job Centre Plus, Maximus, the DWP....with no success (on hold forever) to ask "is this right?" "Do you realise what has been already decided "by law"?. But yet I know they have the authority to do what they like, ignore facts and put me through the mill as before if they see fit.

My GP (one of the GPs who now make up the collective of the phone in service who doesn't really know me at all....my old supportive GP has left) says he believes that the Support Group no longer exists and that there is some change to move people to UC or PIP and that may be why I am getting an ESA50. He's writing a short letter to say "things are the same and she's still having treatment for a worsening condition" but not happy to go into detail about what I can or cannot do on a daily basis (no time he says; too busy).

I arrived at the Tribunal situation in 2012 as ATOS assessors quite frankly lied about me, ignored vital medical evidence, just cut me adrift and left me to fight (or drown as we know many did). It was this website that kept me focused and informed through that fight.

Now, I am frightened to put a foot wrong in what I say or do. I have written to CAB who helped me before (no answer; I am too immobile to turn up at the moment) and have until 4th Sept to get the forms back. It isn't enough time.

Please do you have any advice on what I should do? Or of this situation has arisen before? Can the DWP just ignore Tribunal stipulations?

I would be massively grateful for any guidance. Should I just challenge this form on the basis of the Tribunal comments? Or fill in the form and fight again? Or be applying for some other new benefit that replaces IB or ESA Support?

With many thanks
