called and left no message

Called but left no message. I live in Illinois and the call came from Missouri.

Recorded message concerned about my Google Plus.  Whatever

Automated voice message about my google plus for my company, which we did set up. However when I was typing the number to find out if it was a scammer by the time I answered I missed the message so I am not sure if this is a legit call that wants to confirm my company's google plus listing, or a telemarketer trying to sell their services.

Robocall about Google Plus. Caller ID said "Sedalia MO". I listened to about 10 words and then hung up.
