Does it also have the same issue in Google Maps or Mapquest? As far as I know, the only resource available to you is precisely what you've been doing: reporting it on your phone as an incorrect location. Perhaps if it's also wrong in Yelp, then you can report to them as well. On the extreme end, perhaps file a police report about it with the rest of your community and see if they can speak to Apple on your behalf?
I'm sorry to hear about that; would freak me out for sure.
