Same thing happened to me from the above post. How do I get it to stop?

yeah its 8:00 currently and this person keeps calling me once every hour but i dont anwser it and how do i get it to stop?

These are people that wants you to buy some kind of slimming belt, and when you tell them you're not interested and to please don't call anymore, they refuse to respect you and keep insisting and ask why this and why that. They just don't get it. I don't want their products and won't stop calling.  They even use different numbers.  Guess I'll change my phone #

Since they play the music and only seem to speak spanish, I can't get them to stop.  HELP~!!
