Who called from 2137852490

Have received several call from this number (MAVRICK SOFTWAR - 213-785-2490), but if you call it back, get a "Unable to complete this call" message.

I also got a call (at 8:07pm) on a Friday night from this # and my call log said Mavrick Software. It rang twice and then stopped. When I saw 213 area code I didn't initially pick up but then I got mad that it might be a solicitor and so I picked up. It was a dial tone by then. So far no more calls. Grrr.

Got a call, they say theyre GE, who made the alarm in my house, asked if my contract was up and if id like to switch.  Told them no.

Keep getting calls from this number on my cell phone tried calling it back and it said this number is no longer in service.  How can I stop from this number calling me?

same drill; phone rang twice when I called the #, rings no longer in service; I am on the do not call list and renewed it recently; so now I have deployed my call blocking feature but I hope these people get caught as I'm sure they are doing things like reading phone lines, using my number, for who knows what, and given that AT&T no longer sends detailed billing with the exact numbers called, there is no way to know!
