I contacted Microsoft support this evening via their web page, requested a phone call and was contacted within 1 minute from phone number: 425-635-2970. During this call I was told I needed to speak with their tech support but the transfer line was down. They suggested I call their tech support directly using this phone number: 866-425-8809, which I did. I spoke with "Julia" who transferred me to Surface support (mistake) who transferred me back to "regular" support who helped me with my computer problem by remoting in.
During the remote session/phone call combo with the friendly Microsoft associate who helped me I received two unanswered calls from 1 (800) 642-7676.
Is this 800 number legit? I honestly don't know. I was helped by the call I requested to Microsoft.
