confusion...cubed

thankyou @Chloe_Scope. i had filled online dwp disclosure request when initially recieved the form esa3.  They wrote back and said they had no record of me claiming benefit within that time.  Apart from being bizarre,given they sent me a form requesting the info for that time,I have been on it (incap\esa continually since around 1994.(ish),tho they changed the name a few times...I have repeated online request form re-details.  The housing /rent account ones indicate info i dont know that i was ever really aware of. i am waiting on appointment call back from citizens advice.i will update if and when i learn anymore.thanks

hi again..am still twirling in circles...from the notes of working out dwp sent.. from 8/09/12 the total is £139.60. the housing details i obtained indicates carers was claimed by  now ex partner on 4th oct..the dwp notes  then include this from 06/10/12-14/12/2012. the total now shows as £118. 
the housing details indicate they called at my home on 18/12/2012.i was confused and oblivious that ex partner had solictor lettered them indicating he was moved out.as i was distressed they felt inappropriate to continue house benefit form at thast time.on 9/1/13 it looks like they filled out and did imo referral to inform about benefits.
so. a)i only vaguely remember any of this happening. b)in the scheme of things would it make any difference. and should i print out the house stuff and send ie mandatory reconsideration-or is ex partner claim carers then leaving ,telling council before told me irrelevant.
