Re: Hang up by numbers app - Marketing company, Survey
That would be good, but I have actually done this: responded to the telemarketer (who had called many times previously), saying, "Hold on while I get my father. He's been wanting to get [whatever the telemarketer was selling - heating duct cleaning, I think]." Then set the phone down. The TV was going in the background, so the caller knew the phone had not been hung up.
I checked the phone two hours later. The call had ended, and he never called again. I wonder how long the telemarketer waited....
Ah, the fun you can have when you're retired.
