Are all those affected been rehoused yet?
A better question is have they been offered housing yet, as there is a distinction between not being offered housing and declining an offer because you want something different to what is offered.

Finding 158 permanent homes, in a borough (or surrounding boroughs) with housing shortages is never going to be quick. Even if the council went to the housing market to buy properties, it would take a lot longer than 3 weeks.
The agitation of the survivors by some political segments is probably making their situation worse as well, due to the constant pushing of the idea that logistics and delays are political, not reality based.
