Pip assessment and decision letter

Hi everyone,
Would like some advice regarding the above subject. I attended my pip review f2f and received my consultation report and decision letter, I've found a lot of discrepancies in the report starting from the first page where it was stated I rose from the waiting room chair using my arms to push myself up , when in fact I was already standing up ! Was reported that I walked with my stick more than 20 metres without stopping when I did stop to rest after a short walk due to the problems I have with my spine ( waiting for a procedure to try and ease the continuous pain I have 24/7 ) I also suffer from mental health issues. Onto the assessment in the room , it was stated that the muskuloskeletal examination took place which I can confirm did not and apparently I passed all the relevant tests apart from a few minor things ,no problem with grip , normal strength in both arms and legs to name a couple of things . I gave the assessor more than 25 reports of up to date medical evidence to support my mobility and mental health issues including a print out of my prescribed medications , the assessor who was a nurse by the way only took 10 of the reports , saying that these were all that would be required , my prescribed medications was not included nor was any reports regarding my mental health issues and in my report only 2 out of the 10 was actually included ( i referenced them with what was said in my report) also the corresponding dates on the other 3 which was supposed to have been sent off did not match to any of the letters , it was stated throughout the report that there was no mental health input for my mental health issues when I obviously gave the assessor medical evidence to support them but was told it was not needed and wasn't included to be made available to the decision maker . I also have other medical issues to prove I can't carry out day to day activities, shoulder impingment causing problems moving my arm , heart problems which are still under investigation and more which are too long to list , the decision letter stated I was going to be entitled to standard for both daily living and mobility (Been on enhanced for both previously) stating there was no medical evidence to support my mental health issues and no problems in my muskuloskeletal and mental health findings ( the seven series tests and 3 stage commands aswell as calculating change and spelling 'world ' backwards never took place ) I'd like any advice as to what to do or say to dwp regarding a mandatory consideration, because I believe A!1i have been underestimated the degree of my disabilities and consequently underestimated the extent of my mobility problems and the difficulty I have carrying out daily living activities.Any advice would be greatly appreciated.

Thanks for replying Gordon , I have multi level degenerative disc disease in my upper and lower back and mental health problems, plus other health issues .too many to mention , the activities I should have got points for ( engaging with other people face to face , making budgeting decisions, managing therapy or health condition ) the hp stated on them that I have no mental health input when I gave her numerous reports from consultants and the mental health authorities to prove it , but she never included any of them to be sent to the decision maker hence 0 points for those activities. I provided at least 25 reports from all the doctors and consultants I'm seeing for various conditions, she took 12 to photocopy, but only 3 are included in the report , none regarding mental health input.all in I received my decision letter and it states that my musculoskeletal examination ( I never had one offered to myself ) and mental state examination (didn't get asked to do the 'seven' series, follow three stage commands etc )all in all the report was just full of indescrepencies from start to finish, just wondering what the hext best step to take.
