Last time they called - 4th or 5th time, I pressed to get thru to an operator and then pretended I couldn't hear them so they would turn their phone up. Then blasted the phone with a sports marine BIG HORN. I hope that left their ears ringing.
Actually, if you were on the DNCL they wouldn't be calling you, and the government setup the DNCL - and spent millions of dollars advertising it - for that very purpose.
My cell is registed on DNCL - right from the beginning - just recently I have received 4 telemarketing calls. Even though I dont answer, costs me .20 each time. Getting annoyed.
Going to register on DNCL again, not that it will do much good.
