Caller ID says Carnegie PA. No message, no one on the line

Received call answered no one there then disconnected

Carnegie pa 412-200-5849
idiot starts off with saying it is a survey and goes down hill after that, scam!!!

this number 412-200-5849 has been calling my home for weeks nothing shows on caller ID but number . when I answered  no one says anything .My cell phone said it was from Pittsburgh, Pennsylvania. I thing it is someone using 3-way calling to steal data from cell phones because the data was run up on my cell phone  I had my number changed and got a print out of my bill and it had the numbers 865-224-1897 & 865-224-9189 these number are us cellular numbers came from same phone just had number changed that is all I could find out and the data was rerouted from these two number but couldnt find out no name from us cellular maybe someone can look into this.
