It seems you have tried this procedure: Add or fix a road , Am I right?
Sometimes it can be difficult to have a road name approved, if the change is recent. A better option can be to report the issue to the Google Maps Help Community for them to escalate the issue to the team.
Make sure, when you post in there, to add a link to an official Map where they can check the correct information.
In addition, local authorities can partner with Google Maps to improve your area’s geographic information on Google Maps, especially if the changes are big. Please read Get started with Geo Data Upload . You can share the link in your council, for them to upload the correct information in Google Maps.
As you wrote in Idea Exchange, I also wants to let you know that we have a specific area (How Tos) where we report our issues. I am tagging @Giu_DiB to move your post in the correct part of Connect.
