PIP reassessment upgraded, should it be back dated?

bethlehem

hi, I have been in receipt of pip for about 3 years with my claim due to expire in June next year. Around March I was sent a basic form asking if my condition had changed I said no it was as I had described it in my original claim even though they had not agreed with everything I said. I had a f2f at the beginning of sept andrecieved a decision last week dared 23 Nov. I have been upgraded to enhanced but only from the 23 Nov. Surely this should bebackdated to, at the very least, the f2f if not the form completion?

Sorry but you only get it backdated on your first claim 
On a review it goes from when the decision is made
