I called the number back, it said that it is Gallop polls. The recording stated that they only call to get your opinion on the subject they're calling about and that they will probably call you again. In the recording it also states that they'll never give your information to anybody without your permission. Either way, they're annoying, and never leave a message, or have any information as to why they're calling me. I wish it would stop .

Said they were calling from Gallup.  No Caller ID with name showed up.

Gallup. Surveys.

Just got a call just elevator music playing was actually kinda creepy

No message. I've saved this number to my caller ID under "scam" so if they call again I'll know to ignore it, or answer the call and repeatedly press the # key to signal the robo dialer that it's a nonworking number.
