I was thinking this exact same thing my esa50 form had to be back by 08/06 then as soon as I sent that back I received a pip review form I had that sent back by 08/07 I've been given a date for my f2f assessment for my pip but heard nothing from ESA not sure wether to keep waiting to hear from them or to give them a call hmm
I guess whether you chase them up depends on how happy you are with your current award. if you are happy, it might be best to leave well alone as your ESA will carry on being paid at the current rate for as long as it takes.
