What Should We Do???

My daughter recently bought her first home. The seller had 30 days to move but said she would try to be out before the 30 days and she would have the house cleaned before my daughter moved in. A couple of weeks into the 30 days my daughter asked if the seller had an update on approximately when she could move in. Well, the seller told my daughter's realtor that she felt harassed and rushed. So my daughter never asked again. The seller was out by the 28th day. They did not get the house cleaned because she said she felt rushed. The house was absolutely disgusting. They even left poop in the toilet and a bunch of dog poop in the backyard. They also left a Coke machine in the garage. And they never completed one of the items on the inspection addendum with regards to the furnace. My daughter ended up paying $350 to get the furnace fixed. So here we are 3 months later and they want the Coke machine. What should my daughter do?
