Who called from 3023946944

I am so tired of all these spam calls and have reported them to the "Do not call" but get no results.  So I have taken matters into my own hands.  When I get an unknown number, I just answer the phone and hold down the # key.  This will call a shrill sound from the phone.  Sometimes I even get playful and keep hitting the # key so it is short blasts.  Hopefully they will soon get the message.

I got a long message about lowered interest rates or something. I'm in Oregon.

From delaware but didn't recognize the number.left no message

figured out the calls are based out of Saintclairsville OH.....the Delaware # is a front. Called the 740-338-2084 number, a recording ask for your 4 digit pin???

I never answered.  I figured as much.  I have gotten calls from that same number before and they didn't say anything.
