For a client I am updating website and company pages on Google+, Facebook, etc. However, the client lost his username for Google+; we tried recovering it using potential back-up email addresses but none of these worked. I do have access to the website the Google+ pages is linking to, and the home address that was used to verify the company.Anyone has any clue how to recover this information and regain access to the Google+ page?P.S.: I checked the FAQ but the problem isn't covered there.
