[***] automated call for some law enforcement charity; police association or some such nonsense.

I have customers in OKC, so I returned the miss call a few weeks ago.

Don't do that!  Once they've got your number, they'll never leave you alone. I have since blocked it, but my phone will still ring once or twice before my call blocker axes it.  They're relentless.

I got another one just now.  I did not give him chance to talk.  Told him take me off his list because I five to my local fop and I hung up.
