Ring App Won't Let Me Register My Address

Well, it was a nice gesture. Received the Ring doorbell as a gift. Two hours into it so far and I'm not able to get the app to work. The problem started when I attempted to register for the first time, only to be told my email address was already in use. Impossible, I thought. Looked into the existing account and someone had registered with my email. How?? Don't they need to receive a verification email from Ring? So I requested a password change and, sure enough, I received an email and quickly changed the password and also confirmed two step verification. So that seemed to be taken care of. Next, I attempted to add my address to my account, but the app won't allow it. I called Ring support and was told to use a different email because MY email is registered to someone else in another state. WTF?? I suggested they wipe the existing account and let me start fresh, but I was told the that cannot be done since the other account holder registered first. Ring is being returned. How can a company selling security be so insecure with customer accounts??
