PIP appeal!

Hello I'm new here and wondered if I can have any comments or experience from anyone who may have had a similar situation.
I was awarded middle rate on both counts of PIP on my 1st claim in June 16 at a home visit. I applied to have the mobility part raised to the higher rate in November 16 due to my mobility deteriorating. I attended an interview at a Capita office. As a result my whole claim was revoked. I scored zero on every single count for both mobility and care!! I though this was a mistake although the interviewer seemed stressed and she said she felt unwell and had been having computer problems.She also took a dislike to me as soon as we met. I have had the manual reconsideration. In this I raised each point in turn and explained in more detail about the aids and help I receive, but the person did not comment on any of the details I highlighted and basically just reworded what the original person had written!
I have now taken this to appeal and stated I want to be present and am awaiting an interview date.
I am enquiring to ask if you have been through this and what was your result? I have also heard that a few people who have gone through all this...and have had the decision overturned without/before the hearing had taken place.
I would be grateful to hear your experiences please Thank you x
