PIP Tribunal

Hi. I'm new here.

I had my PIP telephone tribunal last Wednesday, and I STILL don't know the outcome! (I have rung the courts/DWP almost daily, but they won't even begin to consider sending it to me by ernail until tomorrow as it's been 10 days)

Anyway, when I spoke to the Dwp, they said that my case was with a case manager  who would ring me back that afternoon. They did, and i missed the call. I rang back and was asked some questions by the dwp employee. These were: Have I ever been in hospital  care, custody or abroad since I started my claim (no), and are my bank details still the same? 

Why would they ask this??

Thanks
