Who called from 5168000000

This number calls the house every day and says nothing.  It is beyond annoying.

They have been calling every morning with same line about being from Microsoft.  Pretty sure they are Nigerians up to criminal acts!

I keep getting calls from this number. I picked it up once (2/12/14) no one spoke and hung up, or I reject the call and no voicemail is left last time was 2/13/14. Quite annoying

Calling me too several times a day.Same as with everyone else. Man with heavy accent. Claims to be with microsoft. Knew it to be a scam right away. Have ignored calls, answered and threatened to report them, but still it continues. Extremely annoying!!

They are obviously still at it. They have been calling my home since 2/25/14. I did report to do-not-call. I see where the FTC caught and fined the perps in Nov 2013 but obviously they have not stopped. I never answer the phone. Most annoying.
