Thanks for reaching out, Joshua. If someone already claimed your business on Bing Places, you can request ownership by signing in with your Microsoft account, selecting your business on Bing Maps, and choosing “Claim business.”
Bing will guide you through verification to confirm you’re the rightful owner. If you no longer have access to the account that claimed it, you can submit a transfer request directly through the Bing Places support form here: Bing Places ownership transfer
Best,
Arlene
