PIP negative assessment feedback - help please

I have never claimed before and due to numerous health conditions and the fact I cam now only work part time, I have applied for PIP. Had my assessment today at North Mamchester General. The assessor said she would need my meds and prescriptions later on then never asked about them again. She also told me that Syringomyelia and Pilonidal Sinus were the same thing. We ended up in a heated debate and I asked what her position was to which I never got an answer. I then explained how unhappy I was and that I would like her to add my comments to her notes. She was very unhappy about being questioned even when I explained that the two conditions are not the same and I was concerned that she was making assumptions like this and typing notesup based on her assumptions. I raised my reservations about the notes on her report due to this. I was in there 50 minutes from start to finish and dont have any confidence in how this was conducted especially as the decision is based on what this assessor has typed up. I was originally told the respinse would be 2 weeks after the assessment yet my assessir tokd me it would be between 6 & 8 weeks before a response. Should I wait for my response or raise my concerns now? Also not sure how to even complain or who to.

you ask otis or capitor to send you a complaints for id but they didnt send ,make noted of when and who you spoke too xx

Thank you, I was just concerned as the assessor didnt seem to ask me that many questions which all the guides seem to suggest. There was no indepth questions about the real impact of all my conditions and even ignored the fact that all my conditions have had an impact on my stress levels. I have never claimed before and amd working part time so have neen put in this position through no fault if my own. Also the fact that the assessor was making incorrect assumptions without even understanding what the conditions are and became extremely displeased at the fact that I questioned her. It was very distressing and didnt feel it was dealt eoth in very professional manner. I have had to work part time now but it felt like she was making a judgement as if I shouldnt be clAiming if I can go to work. Ill call next week and ask for copy of the report as Im concerned at the responses she has typed.
