istance Program Abuse?

I have a question regarding people on istance programs or people who know about the programs. I am not on any istance and am not looking to be on the programs. I just want to know what should be done about a situation on someone abusing the program or the rules of the program. My husbands brother and girlfriend have two kids together. They are not good parents what so ever and both refuse to work. Because of this they were going to be kicked out of their apartment because of no income so they got on housing istance. The children live in unsanitary conditions and they are always pawning their kids off on other people. They did the salvation army christmas gifts for christmas that are donated to needy families and even complained about what they received. They got gift cards for the two of them and the kids got toys and clothes. They get cash istance and about $600 a month for food istance. They car recently broke down and they got $1000 paid for which was the total cost to fix the car. I honestly don't believe that they should be on assistance just because they refuse to work. My brother in law used to drive a semi truck but lost his license for leaving the scene of an accident. Plus not to mention that they are on medical assistance. There is no reason that they cannot work. Tonight they even pawned their kids off so they could go drinking for new years. They don't bath their kids that often and have poor nutritional foods offered. (They get junk food and pop, and they are three and one year old) What would you do? And who would you contact to make an anonymous complaint. Isn't it true that if both are able bodied that they shouldn't get assistance and isn't it also true that its mainly for single mothers and that the assistance would be revoked if a male was living there?
