Up to a half dozen calls a week, sometimes twice a day. Message recorded in Spanish. When I tried to call the number back to ask them to stop calling, it was always busy. Today in frustration I pressed the number sign, zero, and the star key just to see what would happen and got through to a Spanish speaking woman and told her that I didn't want calls from this number any more. She seemed surprized and spoke in broken english. When I asked who it was that was calling and why, she only said "I'm sorry" and hung up. A few minutes later a male who spoke no English called (from the same number) and when I asked for someone who spoke English the line went silent, and eventually dead.
