Received a call from 314-627-6631. Found out it is Peerless Network. Searches lead me to this forum. When iI called the number back it said if I wanted to be removed from list I could press '1' etc. Not the same number as above, but probably the same company.
Called me at work this morning, no one there when I answered. Called the number back, a recorded message said that they are a company calling on behalf of a publication we have previously received and they follow all laws when making these calls. Said if I'd like a number removed, leave a message after the beep with the number and they'd remove it from their list.
