Calls constantly a few times per week, sometimes two to three times in a day. A few times they have left a voicemail that just has the caller hanging up however twice a full message has gone through to my voicemail with a recording that says "someone from our security team will be contact you when available" or something to that affect. Very, VERY annoying!
Called my phone at work in the 202. No message. A search shows this number is a landline in Placentia, CA provided by Pac-West Telecom (assuming the number isn't spoofed).
