I also got a call from this number at about 10:00 am. I did not answer the call and the listing said Wa, USA I think it could be a hacker idk it just woke me up an hour before work :(
I have also received several phone calls from this same number within a couple of hours today however they do not leave a voicemail. It says the call came from WA,USA.
I got several calls from this # as well, no message, all within a few hours, early too which pissed me off. Anyways, after reading these posts, I called them back and they said they were degree choice or something like that. They were calling for my husband who had "recently requested information on degree options" (no he didn't. He's so no interested in school.) I told them he wasn't interested and to stop calling. They said ok and hung up. Lol. I usually try to call back these #'s I don't recognize, after a little research. They are usually harmless and part of something from the internet, where they have got name & # info from some form filled out online. That's why you gotta be careful about that.
Hope that helps. :)
