Who called from 4044001179

My phone has been rings throughout the day with this number and a few other numbers that I haven't googled yet. I added it to my phone's reject list. I haven't had to use that before, so we'll see how that goes.

This number 404-400-1179 keeps calling  more than ome million times in an hour all day and all night calling up then hang up i answered and say hello,  clicks and hang up. Someone should report this number.

This number keeps calling my sons cell phone . He is a minor. This needs to be stopped has to be so kind of law against this . What can we do.

I have been getting calls from this number several times a day for about a week now.  If I don't know the number, I don't answer..

I have been getting calls from strange numbers over the past month.  When I do answer it is a person with a foreign accent.  I haven't answered my phone when this 404 number has called but I tried calling it back & it said noone is available & hung up!  I am also getting calls from 000000000 number?  How the heck did all of these people get my cell phone#?
