I called them back to ask them to please stop calling, but they just hang up. They do speak English, or at least know some English!!

Received a call August 15, 2008.  Asked in English, "Do you speak Spanish?"
I answered that I did.  Person on the other line hung up.  I called them
back several times and line was busy or they answered and hung up on me.
Wondered why they asked that question. Are they recording my "Yes" response?
Are they pirating my line????? Maybe I watch too many movies?? Who are these annoying idiots?
