I didn't know that I could just request them to take me off of their lists. I wonder how many calls it will take to get them all to leave me alone. I guess I'll try it.
My daughter had a friend who worked as a telemarketer for a summer. Since then I have treated them politely as they are all just people doing a job. Sometimes I am a little brusque if they have interrupted something interesting but I try to be polite.
Occasionally, just for fun, I will come on to the women telemarketers who call. I only do this if she sounds amused by my opening line. And I keep it as tasteful as possible.
