How To Handle Telemarketing Calls

I just told a telemarketer who called me at home to give me her home phone number. And that I would call them back at their home number.
She says “Well, I’m not at home.”
I say “Well, I AM at home.”
She says “I can’t call you from my home.”
I say “Good, then don’t call me at my home. And don’t call me back. Good day.”
