First, there is no easy way of reporting suspected fraud that involves USAA or someone claiming to be a USAA representative.
I received a call from someone (gave first name only and was unintelligible) claiming to be a USAA managed portfolio representative and requested that I (and he butchered my name) call back to discuss my managed portfolio services. The number was 877-627-2811. The caller sounded foreign, unintelligent, and had a heavy hard to understand accent. Never answer unknown callers and Never return suspicious messages.
@Linda Ann, Those type of phishing calls can be tricky. Great job listening to your instincts to protect your accounts. If in doubt, hand up and dial us directly. When in email form, forward those to Abuse@USAA.com ;)
