I am a Google Local Guide level 6, and I was able to modify locations in the past for places I lived at, my friend's house and places I've visited, Google usually approved those within a couple of days.

I suggest you find a Local Guide with a high level that can make those modifications for you, Google is likely to accept theirs.

I'm already a level 6 local guide and my edits weren't accepted :(

That's unfortunate.

I have upvoted your post in hope for someone from Google who can and is willing to help contacts you.
