Does nobody care when assessors make up lies?

Does nobody care the assessors make up lies and assessments are based on a 10 minute meeting, when medical proof attached to the ESA application as further information says the opposite?

Whenever I've had an assessment, I can tell the assessor is not going to give me enough points by their attitude of things like eye rolling.
However I've always won against them with mandatory reconsideration and appeal.
Although in the last assessment which I won after mandatory reconsideration, she made up a story about how my friend parked in a car park and we walked 15 minutes to the assessment centre, but what really happened was my friend has a disability badge which allowed her to park right outside the centre.
I think they take advantage of sick and vulnerable people who are just grateful to win an appeal, as anybody with more mental strength could sue them for making up lies.

Aren't they just following orders though, so what use would complaining do?
Obviously the assessment company must want people to make things up, or why else would the assessors be doing it so often? The companies much be following orders from the government. or they wouldn't do it.

Then why are the assessors ignoring all the evidence. There are far too many examples of how HPs have completely gone against the evidence staring them in the face and the Decision Makers have backed them up in awarding 0 points.

Only when the claimant goes to Appeal (as Mandatory Review just seems to be another stalling process) do the claimants get their decision overturned in the majority of cases.

It can’t all be coincidence or incompetence.
