I have the same experience. The call is telling me that there is a warrant for my arrest at 11 AM tomorrow. I told them I need to let my lawyer know about this he said have your lawyer call us.
I recieved the same kind of call today. Didnt know what was going on because i couldnt understand the guy talking to me. But the whole thing scared me because he knew where i worked, my social security number and my bank account number. I called local police and i have to go in and file a report. Did he have anyone else's information like mine?
I just got a call from him as well. He had all the same info as well. So we talked for about 30 minutes and he couldn't tell me the criminal case he had against me. I welcome these calls, I drive those idiots crazy. I called back several times but he is afraid to answer I guess.
