I got a cal from a man from india telling me i have been selected for a free trip and shopping spree. He had a lot of personal information of mine including my checking account routing number and was very agressive to get my account number. it seemed fishy to me so i told him i was not interested. would not take no for an answer so i told him thanks but im not interested. he kept calling and left a message cussing me out and said some perverse stuff. i tried calling back and only got a busy signal.
Got a call on my cell phone from 213 337 0021. They didn't leave a message. I called back using my work number and no-one answered. I let it ring and ring, still no answer. Who is this and what do they do?
