You've been downvoted, but I think you have a point. Maps support & "suggest a change" are two different sets of ears, and while one may be deaf to this problem, the other may be more responsive.
I know it is trendy to bash Google but if you get millions of support requests it would be abnormal to forward support emails for something that has a very clear built-in function right in the product. It isn't a problem with Google that they don't reply to mail for something like this. It is a clear user error.
I disagree. The whole cool part of Google is organizing data and writing good algorithms. Even if they get a million misdirected suggestions a day, they are probably one of the best organizations in the world to figure out how to redirect correctly.
