Today at 2:55pm, KQED channel on TV (Comcast) , then I logged into KQED.com (different service prov. for my internet), clicked donate button for a book I want, but didn't finish. Next, Comcast HD box auto-turned off, KQED TV station off, but some others worked. Next, someone phoned from phone #: 123-456-7890 calling about my "MS Office computer"!! I replied: "what is it you do? "Technical Maintenance of all MS Office computers". What is your company name and phone number? "I cannot give you that information". Then I cannot talk to you! I hung up.
