I just got this exact same message word for word except the so called case number was different sounded like a robot calling, glad I decided to investigate this it didnt sound right to me.
I got the same call from 202-836-8580 asking for someone I've never heard of. Says they have 2 allegations against said person and they're going to hunt them down. They keep calling because I can't convince these idiots that they have the wrong person. I've had the same phone number for 17 years and there's never been anyone with the name that they're asking for at this number. These people are idiots and don't have a real job because they're so stupid that no one would hire them.
I would file reports on their criminal behavior at the following three agencies:
Read up on your rights here and also make a complaint at this government site: http://www.consumerfinance.gov/
Also file a complaint with your State Attorney General's office.
