Been kicked in the gut twice

Lost so much money due to this company. Our house was rented out underneath us, after we had an agreement of two months notice. We had no where to go, they found us a furnished 1 bedroom flat, my son is sleeping a stretcher, our furniture is in storage, and our dogs in the kennels. Now they want more money out of a house they forced us out. We had two days to pack up our house. It was so stressfull. We lost 9+k in a month. We had an agreemnet about the situation but they went agains that as well. As if we have not lost enough
