Please use the DONOTCALL.GOV complaint form.  It does work -- the lifeline fraudsters are under FCC and courts to cease and desist orders as of late December 2013.
  We demanded the DONOTCALL.GOV - so we need to use.

This phone number keeps calling my cell phone.  The first time a guy identifying himself with Microsoft with a foreign accent (Indian?) spoke to me trying to convince me that there is something wrong with my pc hard drive.  When I told him I would like to see an email from him; he hung up.  Now I am getting 4 - 5 calls a day from this number.  

Just got this call now 2/13/2014 AT 6:10 Soo this is still going

I just received call from 516-800-0000 at 5.15AM MST.  I could hear people in the background but no one spoke.  I don't know if they are aware of the time zone change but maybe they should talk to someone.  I find it very rude especially since I just lost my husband and don't need this on top of everything else that is oing on.  I also have family members in the East that are not healthy.  I am on the DO NOT CALL LIST but I guess it doesn't apply to the United States.

I just got a phone call from them as well. I didn't answer, and when I tried to call back the call would not go through. Did you have to report them? Or did they stop calling when you said you'd report them?
