I did change the password, but it had reached the point where the impostor had security questions in place so that I could not take certain actions against the account without answering them. Namely, I wanted to delete the account or change the email address so that I could change MY email address to the desired one. There appears to have been a large delay in the system, as I was finally able to change it just now. The support employee was less than helpful in stating this as a possibility, however.
