PIP review and ESA issue

I have recently had my PIP review and thankfully i only had to wait from end October until today and it was all done based of information i had sent previously and new Medical Information i supplied. It has caused me no end of distress the waiting but it is over now. The Query i have is my Partner, we do not live together due to our needs. But he never completed his review form offered no new medical information as he has not been to GP or had any contact with Mental Health since his previous award, now he was contacted by PIP about his form not being returned, (i had offered to complete it, but he needed to ring to get a extension, again he didn't bother) So they arranged for him to have a Telephone Interview, and told him he would hear within 4 weeks, and he did they text him to tell him his award , you could have blown me down with a feather when he was awarded Enhanced of Both components, he was even sent back dated arrears of 2k not from the date the form should have been returned, but from when they posted form to him. Prior to this he was getting £272 every 4 weeks. tbh it has annoyed me a little as he's done nothing to help himself as usual , given s uplift !! whilst others have too fight , going through mandatory Reconsideration and then tribunal to get their award . Now i have noticed since his award apart from that strange code a lot of people had on their bank statements, what would have been his ESA has now changed to JSA , and he had a Budgeting Loan which they are not taking off his JSA, it has appeared twice like that now, i have asked him if he has any other letters from DWP, he just said ''oh there are some letters but i cant be bothered to look''. No as he has been too busy spending money like a fool , going to Pub , gambling and buying Hunting Clothing, not paying any Council Tax or Water Charges, i just can not make any sense of how he can just waste 2k in less than a week!! and not read other letters. I am wondering if anyone else has experienced a uplift in their PIP rates and payments appearing on Bank Statements has changed from ESA to JSA, as i am worried they are doing this to get people moved onto UC ? i'm not due to be paid yet and i am dreading mine will have changed too although on my letter it refers to ESA. Sorry this is very long, but i hope some one finds elements of this of some interest or anything similar happened .

Yes i claim ESA in own right, as we do not cohabitate, i just am very concerned that they are putting people from this latest round of Reviews all back onto JSA with a view to migrating us all onto UC or to get us on merry go round of having to have interviews at Job Centre in light of the Government announcements of making people go to work!! i have found this latest round of reviews very odd as it is, as everyone i know in my area who is on PIP all had a review letter within 2 weeks of each other. My award last time was not due to end until May 24 . just odd . All i can do is wait and see when i get next payment if mine is same ie with JSA . As i was unaffected by Christmas payments mine went in with all the same references on my Bank Statement. Or if i get any letters from DWP i guess. Thank You Gordon
