Medical excemption light touch esa

Hi just a update from my last message question. Still awaiting a reply from advise here. I since requested esa dwp information about if i fall in the catagory of excemption from further medical assessments on the ground of me having the limited capabiliy criteria severe health condition. I have been under this since june 2017. Not been reassessed. I read up damien green then dwp minister disability. Says anyone under this rule would have light touch review if reassessed. They advised they call me back to reassess me over the phone. If my condition has changed or worsened. They didnt inform or ask me this i had to ask them first request it. Then consider if im to be excempt. Im covered in pip for lighttouch 10 year review recently. Can you give me any advice. Is it a new thing dwp ringing up. Is it assessment. Can i be given time to get my updated evidence in. Just let you know and others it may be new thing there doing. So others know they can ring in request a call back. Rather than waiting years for there next medical assessment. Please reply any advice or cautions! I need be aware of so im ready how to answer there questions and im fairly assessed if its via phone thanks can i record the call for example nik.
