Receive calls frequently from this number, leaving an automated number claiming I'm being investigated for fraud. When I called back, they would not identify any names or specifics. Just that I'm being investigated for stealing my car by participating in faudulent activity. When I explained I didn't own a car, the agent got belligerent, started yelling at me, and when I hung up, he continually called my phone for about half an hour.
If the agent is not willing to give you specifics, and becomes angry when you ask for details, they are clearly a scam.
