Received 2 calls from 310-742-1701, one at work and on my cell phone and left a nasty message about an urgent message about a legal matter. Identified himself as Adam McKenzie, but had a very foreign sounding accent. The messages sounded very scripted. Number showed up on my work line as 0000 and on my cell as unavailable. I didn't answer either call and just deleted the messages. I've had similar calls in the past with different names, but very similar messages. I filed a complaint with the FTC and the Attorney General.
I've also received calls from numbers that look like they come from outside the U.S. with 8-9 digits instead of the typical 10 in the U.S.
They called my cell and left a message showing the number 0000, then they called my work showing unknown unknown but left the 310 number for me to call and ask for Kathy, Ryan, or jimmy. I called it and spoke with Ryan who told me I was a prime suspect in a case involving illegal downloads and that armed officers would be coming to my work to take me to the courthouse. Since I had received calls from these same people previously, but under a different number, I told him to send them on, I had notified the FBI and an agent would be waiting for them. They hung up.
