How long to hear from PIP?

@Adrian_Scope i did they said it went in late should be with me this Friday i also got my assessment report will never understand why my b c and ds scored the same but i am going to get it looked at as somethings where plain over looked things that were medically supported i  am also confused as she said i should be assessed again in three years time i thought a new law came in saying pensioners shouldn't have to do this ? Thank you for your advice
