Occasionally, for some professional services google will “create” a listing for companies. I see this mostly for doctors, where Google uses some NAP from directories to create a listing with enough direct searches for them to do so.
So, double check that’s not the case.
Otherwise, follow the user experience. Search for terms you’re trying to rank for, see what the SERP looks like. Find where you are (but keep in mind that Google is using your location data, so if you’re doing it close to your office…) A SERP checker tool would be better for this.
Check your GSC if you have a website. Make sure all your pages are listed. You can also site: search your URL to see all the pages that are listed.
