Caller ID said San Pedro, CA. Scam, sounded like middle eastern accent when I called the number. I told them they were obviously a scam, and if they called again, I would have them arrested for impersonating a Federal Officer. I'll not ever again answer a number I don't know!
got a message @2:45 9/8/15 from David Gray telling me I need to return his call for the same reasons listed above. My number is unlisted so these calls are made using an auto dialer and fishing for fools. Ignore the call.
