I answered them today. It was someone with a thick Southeast Asian accent asking me questions about smoke detectors and fire extinguishers in my home. I told him that I was at work and could not speak, and asked him to please remove me from his calling list. He continued to ask questions and I calmly repeated that I was at work and could not speak, and asked to be removed from the calling list. He then proceeded to yell at me until I hung up.
