I too have received the same incomplete messages from this number. Caller ID indicates TriState. Today I received a complete threatening message indicating who they were with a call back number and name 7707038518 Tri State callers name Janea Williams. Not sure what to do as I have fallen victim to scams before.
got a call but never answer if I don't know whose calling so they left no message called them back the scammers took long for recording machine to leave # really,when you don't know who it is well probably reading all our messages, if they are there welcome to call me back I will be ready with a bull horn if they want to get deaf, oh call me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
