Every day, at least 8 times a day, they call and want personal medical information. My wife answers the phone, it is her phone and number, and no matter how many times she tells them to stop calling, they keep calling back. When my wife answers, she asks who is calling, and she gets the same answer every time "I will f#%$&ing call back later". She tells them again to stop calling, and they call back a few minutes later, always the same person, who doesn't speak English very well. Why do they keep calling when all my household numbers have been put on the Do Not Call list?
