DLA to PIP

I would like to share my wifes recent assessment for transferring from DLA to PIP. The assesor arrived earlier than the appointed time which didn't really suprise us. After the assessment we received the news that she'd gone from higher rate mobility , lower rate care on DLA to standard rate mobility on PIP. Having then read through his assessment I was suprised with some of his comments. Firstly he commented on my wife being able to unwrap a sweet which in fact was a Halls menthol tablet , what he failed to mention was that I'd started to unwrap it before I passed it to her. He also commented that she could open her bottle of water with no problem , if he'd given us the chance we could have explained that after her bottle is opened for her the top is always left loose. When asked about going out and meeting people we explained how my wife has lost all confidence after having a masectomy in 2013 and she only goes out if a family member is with her. I asked my wife to share her experience with him about the time she had to travel on her own unexpectedly to our daughters in a taxi which was only a short journey and unfortunately I was at work and couldn't be with her ,the thought of that taxi ride bought her to tears and I had to explain, but he didn't write anything down, just moved on to the next question. He asked if she could plan a journey, her imediate response was, no chance, then straight away he asked, what about the hospital and she said no, he then went on to the doctors and finally he got a yes. That was hardly suprising considering the number of times she visits the doctors and it only being less than a mile away, I thought we might go on until she said she could plan a journey to the bins in the garden, why can't they accept your first answer. She told him she had problems with painkillers making her sick and explained which ones, he then remarked she was taking no analgesia even though she told him she was perscibed amitriptyline. He went onto the physical test and in his report said she had no problems with but conveniently left out that on two occasions she cried out and on one she stumbled onto the fireplace Finally I asked if I could pass on some more information that we'd got since sending in the application and he told me to either send it to or ring Capita, I rang Capita and they informed me it's nothing to do with them and to pass it on to the DWP. Surely he should have known that and it doesn't bode well for anything else he's got wrong. We are now asking them to reconsider their decision and despite sending in her medical record , they're asking for doctors and hospital letters, which are not easy to get. Any advice would be welcome and apologies for rambling on

Thank you Gordon, she scored 10 for mobility and 6 for daily living

10 moving around 2 preparing food 2 washing and bathing 2 toilet needs . Since the application was entered she has been put on steroids for Giant cell arteritis , and we're currently awaiting the CT scan and blood test results for the cramp and spasm she keeps getting in her hands, we also now know she has rhumatoid arthritis.
