I am also getting phone calls from this number. Not picking it up. I almost got scammed the other day, and from that day on I am getting at least one call a day from 360-718-6589.
Got a text msg during the middle of the night, waking me up. Advertising a $1000 Victory Secret gift card at http://vicgiftcard.com
Going to report it to my cell phone company as spam. I also put these numbers in a "don't answer" phone book entry and set it not use any ringtone. That way if I see the call come in, I ignore it and it goes straight to voicemail.
