Hookers in Forest Hills?

My Super informed me today that a tenant on my floor hires hookers.  Recently, a hooker was not happy with their business transaction and vandalized our building.  He said he reached out to NYPD and filed a report but not much more is being done.  In addition, there are strong marijuana smells from another apartment and when he calls NYPD they take 6 hours to get there.  He said he went to the precinct himself and still no help.  Any suggestions on how to get more assistance?
