Bill Gates has nothing to do with this stuff, nor does Microsoft.
I got a call from India speaking guy in broken English. He told me my computer license was about to expire. I don't him I don't have a computer, he asked me three times and I told him no. He was gobsmacked and I am sure he didn't believe me but, he hung up anyway. No more stupid calls. Almost always I let the answer machine take the calls.
The other day a teller marketer called three times in one day. Next morning at 7:45 they called and dinged a really loud bell. When we didn't answer they called right back and did the same thing. I guess they thought we were asleep. No, we are early risers.
