called my cell phone  says from fl.usa  today at 11:51am

got a call from this number this morning 11:12am didn't answer and they didn't leave a message 4-23-13

I received a call from this phone number and did not answer it. The caller did not leave a voice mail. I tried to call the phone number and received the mesage that it was no longer in service. Very strange! I don't have time for such nonsense. If you're calling my phone and I don't answer---LEAVE A MESSAGE.

Weird that everyone says the call is from Florida when this is a Chicago area code.

Correction: ONE person said the call was *about* Florida vacations.
ONE other person said the *caller ID* said fl.usa.
Caller ID info is easily faked, so the number that you assume is a Chicago number can also be fake.
The call is probably coming from India or Pakistan, on a VOIP line with faked credentials.

Did you get a call from this number? Your post would be more meaningful if you elaborated on that.
