Just started getting calls from this number and another very similar. My audio is broke so i let voicemail catch them and when they didn't leave one I called to see the voice that answers (because I DO NOT get calls I don't know) and one of the numbers had a weird short message that played over and over (the other number) and this number wouldn't even ring when I called it back!
Okay, taking the data broker comment in mind, I gave it some serious thought. I think it's calls from the oklotto site. That's the only thing or person I've given my phone number to recently (hate to miss that lotto call)!!!! LOL.
