I used to see the DWP as a beneficial system, but they are hounding thousands of vulnerable and disabled people for repayments of benefits, often when the person involved did not know they needed to inform the DWP of a change.
I know this from experience when I was hounded for a large repayment because they insisted I had not informed them of a "change of circumstances" when in fact I HAD done so.
