Temporary accommodation

Hello everyone I am seeking advice if anyone has any information, we are a family with 3 children 10,5,2 year old unfortunately the 5 year old has autism and at the moment we are placed on a temporary accommodation after the council put us on main duty I got a call from a lady from the council and offered me another temporary accommodation still unsuitable and was rushing us to make a decision we refused it and she told us that she won't be helping us no more and this was a good will of gesture so any advice? Much obliged
