PIP no award, Help needed.

Hi, my husband is on DLA care at the highest rate and mobility lowest rate Indefinitely since late 1990`s for OCD, Depression and Anxiety, in December 2016 he was invited to apply for PIP, the form was completed and sent, he was then asked to attend a face to face in late January 2017 [Some of what was put down was inaccurate in the MY DECISION part of the failed award letter summing up], we have just received the PIP letter stating they cant award PIP and DLA will end, Total score for daily living 2 POINTS, Total score for mobility 4 POINTS.
I Will be asking a few more questions latter but to start with:-

I Have until the 3rd of March to ask them to look at it again.

1. I Have phoned and asked for a copy of the assessment report, also should I Write asking for the assessment report aswell [its in Wolverhampton] and does it need to be hand written or is typing oki]

2. should I Phone and write for a mandatory reconsideration now or leave it as late as possible so I Can digest what was fully on the face to face when it arrives, on the phone they said it could take 10 days?

Thanks, again I Do have more questions and will ask later, Thought I Would get things started straight away as regards appealing. Thank you again.

Thank you,
What exactly happens when I Ring up to say I want a mandatory reconsideration , Would I still have only until that date to write to them with added evidence and explaining which areas I Think my husband should have scored points [as per your PDF on appeals] or as soon as I Ring they look straight away at the form plus evidence I Had already sent ?
What Im trying to say is if I Ring and write saying I Would like a mandatory reconsideration, Do they then send anything back to us to fill in or does everything need to be sent to them before the 3rd March.
I Am considering sending evidence from my own Doctor to confirm that I care, support Etc. both my husband and son and Im just about at breaking point myself
Sorry for the questions but its been a tough few months and Im exhausted.

Ok thanks,
Last question today, Im looking to gather evidence and letters from relatives, friends Etc. explaining for example how without my help Etc. my husbanc would not be able to take medication, eat etc without prompting would these letters be ok, also I was woundering if my husbands Doctor could do the same but is it possible for his Doctor to know the help that I Give certainly regards his medication and write a brief letter of support ? j [Which is wrong as in the face to face it says he can take medication fine on his own, but not true] I Suppose the doctor would remember the overdose taken so now I Administer medication, Any other ideas as to what to send would be great, Thank you again.
