Yes, sometimes it works, but more often than not on Places claimed listings you get the most ridiculous answers. The timeline can also vary like crazy, I've had Report a Problem items finally worked on a year after I submitted it.
Even the spam team can be frustrating. I have a network of "luxury apartments" right now that we're having trouble convincing them to take down. It basically works that if you own a strata apartment that's available for rent, you sign up with this company and they will promote it as an executive suite (single apartments, not entire buildings). They put a marker on every apartment across the nation. The spam team is fine with this because they've been Places verified and thus must exist. We're giving them one more chance and then it goes to a different team; we have multiple options.
But back to what you would do next, yes, next is Map Maker. If it was just keyword stuffing the name, you would fix the name. But this is complete spam, so use "Delete" and under the options choose "Spam/Abuse".
