Towns, roads and squares are elements of the Map Layer. Local Guides cannot edit that layer. Only Google Maps team can.
What we can do, for helping the team, is to report an error on Google Maps, through the “send a feedback” that you will find scrolling down your menu on Google Maps.
Please take into account what @ErmesT mentioned in his comment. I am going to re-label your post to How-tos, where you can ask questions or share tips for Local Guides who want to make more helpful contributions.
@ErmesT I just wanted to let you know that I added the accepted solution to your comment.
