Did not know the number, so I didn't answer.
I do not have an unlimited plan on my cell phone, so it gets annoying. Ny cell is on the DNC list, but they do it anyway.
I get these calls every so often, usually at the most inconvenient times. I don't understand how these people make money, because everyone has caller ID nowadays, and most people don't even bother answering if it's a strange number.
