I also had a missed call on my cell. Called back & it was no longer in service just 30 min. later. But I recently had an unathorized purchase in a market in this area. I live in a different state. Seems suspicious!!!
Got the call on my cell phone. Was a recording of a woman speaking Spanish. I understood the words, "muy importante", but hung up. The area code was unfamiliar to me and don't know anyone in Missouri.
