Bold scammers attack today

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.
