DLA to PIP

Last year I was asked to move from DLA to PIP, having been on DLA,mobility component only for over 20 years. I filled the form in myself, gave medical evidence, my condition had worsened over the years, plus I had been diagnosed with other illnesses. Had f2f at home, she was a nurse, very friendly which put me at ease. I told her since id sent in form id a new diagnose, following MRI scan, asked if she wanted copy of letter, she said no. I was awarded standard daily living and mobility, meaning my mobility car. had to go back. Getting daily living meant iv more than when just on mobility. The week after f2f I went in hospital for injections on cervical spine, I had a bad reaction to injections. I really could not cope with doing MR, However, when I got report from f2f I was shocked at number of lies, so I did complain, but of course they backed the assessor. I hope others are successful in their appeals. I'm concerned it takes such a long time, if it goes through to Tribunal.. Does anyone have info of applications that are going to be reviewed by DWP?
