"They" don't call. Their computer does. Nothing you say or do will change the picture. Once the computer registers that someone answered, your number will ring daily forever. Re employees "on the clock," it's likely that there aren't any employees. Just the same criminals who set up the scam. If you do play along, try giving them the address of the local police station.
Called my phone provider, (AT&T) needless to say I was very upset when I put my foot down and stated, they needed for me to have a way to block these massive calls and harassment or I was going to find another provider.
They set me up with Privacy Manager Feature, it is at no cost to me, About time, Please check to see if your phone company offers this.
I have a call blocker that makes me laugh EVERY TIME THESE IDIOTIC CRETINS CALL ME AND THINK THEY WILL OBTAIN SOME OF MY CASH.!!! My blocker shuts them off the moments it hits BUT I still get to see (sort of) who is calling. All these jackazzes spoof their numbers and names, so the only good it does me is to block their stupidly spoofed number HAHAHAHAHHAHAHAHAA. Dear Federal government I believe these spoof callers are terrorists that want to get our money to buy more drones and bombs so they can strike revenge upon us as a nation!! STOP THESE PEOPLE WITH THE TECHNOLOGY WE HAVE YOU CAN DO IT SO DOOOOO IITTTT!!!!
