Back in 2019, when I had my review, I had an assessor who was extremely rude to me and my carer, and told my carer to shut up and was rude to me as well, and had no interest of doing a fair assessment. She basically scored me 0 points on everything, my carer appealed, i got my PIP back in 2020, only lower daily rate
My carer got a phone call from PIp today, talking about this review in 2019 and how DWP, admitted the assessor was rude and nasty, and didn't do her job properly and they upped my points seeing as the assessor wasn't fair and DWP had a further look at my forms for my last 2 assessments, and felt i should be allocated more points, and felt like I was being penalised for no reason and they admitted they got it wrong. I don't think this assessor works at the DWP now, so I assume, they had a few complaints about the assessor.
I'm also being backdated £5000 from 2016 due to a change in the law.
