If the same thing happens, I suggest contacting our Phone Support Team so they can look into your account in a secure environment. They also have the tools that can do advanced troubleshooting steps in resetting your password. 

I'll be sure to keep an eye out for your response. Please let me know how this goes and if you have additional questions or concerns.
