I received a call from (213)266-7231 at 12:00pm, on 06/27/16, i didn't answer because i didn't recognize the number. They left a robo-message stating that i had won a trip to the bahamas. It's a scam. I've received this call before from a different number regarding a trip to bahamas. Even when i asked them to stop calling my number, they just changed numbers and continued calling. They just want to know that someone answers at your number and they start robo-calling when their live agent isn't successful. There's no way to stop them except getting a call blocker gadget or paying a one time fee of $19.99 for magic-jack to block these calls. Smdh
