The usual call and hang up when the machine gets it. It shows Bardstown, KY. I have had a previous call from 502-9172, so they must use a bank of numbers to harass people. I never answer calls I don't recognize, so they are wasting their time. I also enter their number into my call blocker after they call twice. BTW, I have no debts, so it is not a collector, just some [***].
