Advice for benefits board post

Hi Guys, I asked a question regarding my sister-in-law which I received good advice.
A poster post 8 BillAndJean commented on their friends situation which seems outrageous from the point of the small sums involved, and threats of action after 30days I think your advice would be appreciated http://forums.moneysavingexpert.com/showthread.php?t=4640479

I thought I would link this thread to my reply
