yes this happened to my friends and i and we are SUPER worried...he's a creeper!!!

The person sounds like they have a very thick Hispanic accent.  I think it's a Pueblo, CO cell phone number and I don't know anyone there and I definitely don't know this number.  The first time they called they left a message ending with "I love you."  And have called four other times in 2 days and didn't leave messages.  I answered once and told them they had the wrong number but they keep calling.
