Do not pick up this is a telemarketing company

Received two calls from this number, one immediately after the other. No voice-mail. Appears to be a telemarketer.

I had some type Craigslist and I think that's where they got my number. It's my work number and I got two calls yesterday no one when I pick up and then they hang up. They called me again today a day after they called yesterday very annoying.

Just got my first phone call from this number.  I did not answer.  No voicemail.  Monday, 4/7/14, 5:11pmCDT.
