Lying professional assessor

As some may recall, I recently had pip assessment. All seemed in my favour, as well as a promise from the assessor for the mobility component due to my epilepsy. Received copy of report and seems I've got someone else's report. No I hadn't. The assessor has lied. On every aspect she has disagreed with my disability (not just E). I told her for instance, I last had a seizure at the end of June while in hospital following 4 stents and having  a heart attack during procedure. She reported my last seizure was March and that I thought my seizures were controlled.  I last saw my neurologist on the 21st June. She reported that I hadn't seen my neurologist for many months. The lies go on and on. I think she realised I was weak had no confidence, no self esteem etc and thought she'd strike me off the governments list of burdens. How wrong was she. I'm waiting to see a professional person who specialises in these disputes. If her decision is over turned in a tribunal  can I perse to sue her for ********* of character and lying.
