Who called from 6165974101

I received the call today for the first time...hopefully the last.  But caller ID said it was from "TN Removal Line".  I have no idea who that is.
Don't plan on calling them back.

Calls come in from this number once or twice a day. Sometimes there is no message left, sometimes there is wierd noise like a very slow distorted audio signal which resembles heavy breathing or lions roaring. Very annoying.

Got a call today from this number.  They asked for me by name then hung up.  I called the number back several times and i keep getting hung up on.  Weird

called here and did not leave message.  said "tn removal line"

Got call tonight from this number.  First time ever.  Nobody said anything but there was strange noises like a distorted voice or lions roaring.  Then they hung up after a few minutes.
