Who called from 3607189385

I didn't answer. They called my cell, so I wasn't about to confirm my identity. Research shows the # is located in Vancouver, WA. Called 7:30 pm

I received a call from this number March 20th 2017 at approximately 9:15 am. I didn't answer it, but a few hours later, I called the number back because I couldn't find any info online about the number. Anyway, the recording said it was a survey company. I'm not sure at this point if it's a malicious company or if it's safe. But I just wanted to get out what I found.
