Being Evicted by Ashford Bought council

2 sisters living in a 2 bed flat. Are being evicted after their brother is release from prison after 7 years. The brother was allowed to let his sisters stay their while he was in prison. The problem is his not allowed to live in that area.
So why was the sisters allowed to stay their in the first place if he cannot return after prison.
Because of this they have made it their home and are well liked in our small village. They have family pets 2 dogs 4 cats a rabbit. All well looked after and loved.
So why split them all up!!
The council will have to re home the sisters. The animals will need re homing to.
Its not fair. We need to keep them together. Please help. Let them stay in their flat.
