Sounds like probable bill collector - calling for my son - left message to "call Kevin at 888- (didn't catch the rest of the number), in office central time"
This number called me and said his name was jack. He asked for me to call him back by 8 at 800 number. No last name was given and he spoke extremely fast. Sounded a bit foreign.
This number called me with the message "This is brad williams from first financial bank, please call us back at 1800- message deleted, you have no more messages" Freaking weirdo.
