Welcome to the Q&A Forum

Calling them and I was able to get it unverified and then I could reverify with an account I had access to.  Thanks for your help!

Thanks for the response, but I am still stuck.  I have tried that, but I don't know what email or phone may have been used.

I have a client who verified their google+ listing, but doesn't remember what email they associated with their account.  Any idea how to reverify or discover the email?
