ESA changes ?

My wife is on ESA. She gets a reduced rate of 70.00 per week reduced because she has a pension. She is in the support group and has been for some time.
The query which is worrying her is that when she was last paid it didn’t say EESA on the bank page as it always has it said JSR….and the amount has been reduced but only by a very small amount,

Can anyone shed any light on what is happening?

Many thanks .

Sorry Charlie, I don’t. Perhaps ring the DWP to find out.
