Do you call the housing department every day saying what your neighbours do etc., you need to keep on at them.
Even say its making you ill and maybe even frightened to go out!!! not sure if this is the case,
Im sorry to say i had similar situation 4 years ago.
I lives in 2 bedroom flat with 3 children and i kept on at the housing department every day, i was 11 floors up and was cramped, in my case both me and my partner worked, and not until i finally managed to buy a house and about a week before i moved out, did the council offer me a 3 bedroom house, well you can imagine what i told them !!
st1ck it!!!! it annoys me and im not prejudice but people come in the country and get housed straight away yet there are people like yourselves who are desperate to be moved and can't mainly cos these people take all the homes that become availiable.
