Looking for web app or theme for citizens complaints

I am looking for a web app, a theme or a plugin that allows me:

to have a map where people can click an address to report an issue/problem/complaint/request at that certain address (a city map where you can create a pin with a complaint to be seen by the Mayor of the city)

Like this one:
