Male caller made numerous obscene phone calls to business

Called at 9:20 this morning on my work phone.  Indian man left voicemail stating he was Officer Sean Peterson from the Financial Crimes Investigation and that there was a legal case with my social security number on it. He said to call back 213-799-0972 immediately and if I don't "Good luck and have a nice day".  I am so tired of these scammers.  They last called on September 30 from a different number and now they are back.  I refuse to pick up the phone when I see these idiots calling because one time I made that mistake and they we very threatening and after I told them I owed them nothing, the idiot called back every minute for 20 minutes.  I have no outstanding loans whatsoever. These people need to be stopped.

Same story as BC's, although I never got far enough into conversation to get a phone number from him.  He was rude and hung up on me when I got back in his face.

This caller left a message on my voicemail that was very hard to understand, as he had a thick Indian accent and a lot of background noise.  He left a North Carolina phone number for met to call him back at.  This number belongs to a residence.

He also said, "If you do not call me back, I wish you luck".

Again, thick Indian accent, said he worked for the FCI/FBI (couldn't quite understand what he said), investigating some woman for fraud. I said I didn't know her, and then he asked if we could be friends.
What a creep.
