I'm posting this on behalf of my mother-in-law who doesn't have a computer but got two "Windows" calls (2 different numbers) in the past couple of days. One of the calls was early in the morning and woke her up. She is 95. I will have to show her how to block calls, but of course these people "spoof" other numbers and get through by using a different number every time. When these lovely Windows people call my home, my husband or I sometimes try to see how long we can keep them on the line, following their instructions, wasting THEIR time. I think our record is about 20 minutes and then when they finally realize, they swear a blue streak at us. If you try to talk to them ("do you realize what you are doing is a criminal activity?") and try to engage them in a conversation about what is so wrong in their life that they must stoop to this level, they hang up. I envision some Third World call center full of men who can't find a job anywhere else, with mouths to feed, so desperate to fill their daily quota they can't even tell if someone is stringing them along. What is wrong with this world!!!
