I got a similar call at 3:13 PM CST I did not get to the phone in time so I tried to call back and got only a busy. Then I found this web site and added my info. I am in area code 618
From your report and some below, it sounds like they're targeting cell phones. They called my cell at 9:04 AM CST today too. Steph says Bahamas cruise / survey scam... been getting those on my landline number a lot lately and I've actually had them leave a message or talk if I happen to answer.
BLOCKED!
It's a robo-call scam. I answered since I live in Chicago and it's a 312 number. But it's just an automated message saying I "won a cruise." Hung up and blocked.
