I have received a We're reviewing your benefits and circumstances letter,stating I must attend this interview I am rather confused because I was awarded PIP in 2015-2016 until 2026 so I am very confused why I need to go and produce all sorts of documents like bank statements etc. I am aware that PIP is not means tested so why should I have to show all these things, I am ringing them Monday morning to ask why I have received this letter , Does anyone know in the meanwhile why I should have to do this. It is very distressing .
