How do you handle phone calls from telemarketers?
I politely tell them I'm not interested.
If they do not stop their spiel and thank me and hang up, I interrupt them and say I really am not interested.
If they persist I say, "please get your supervisor on the phone I would like to speak with them." they usually hang up at that.
More often then not If I am polite they are polite and they wish me a good day and we all move on with our lives. It's a crummy job and if I had to do that to feed my children I would not want people to cuss and swear at me for it.
