PIP

Hi since of August 2020,ive been unable to work due to hip osteoarthritis in both hips, I claimed for pip in November of the same year, I had my assessment in January 2021,3 weeks later I received my decision in which I got zero points on everything, the assessor had lied, with my condition I have pain from my lower back all the way down to my knees, I use crutches to get around, I've had to change my extra reception room into my bedroom as can't manage the stairs, I don't drive because of it, but apparently I drive an automatic car, my daughter does the cooking, as can't stand long enough, she helps with alot of things, which I told the assessor all of this, but still got zero, I've appealed the decision hopefully I get a better outcome, but this had made me really low,
