Depends on what is the requirement on informing residence on
this currently.
Ideally, flyers should have been distributed to each household on
top of the notice at the lift. And if the household is blind enough
not to see either, then I see no reason to blame the maintenance
people. If these are not done, then complian should be made.
However, I suspect that this may not be a required procedure. This
means that according to law, there may be no party to blame for
this situation. In that case, my ideal solution out of this is to
have the government to pay the compensation out of good will and at
the same time change the procedure requirement. Of course, I am
assuming that this is not part of procedure at this point in
time.
