@YouTube Got problems with my monetization.. Got demonetized for duplication..
But every Video is mine and it must be a mistake.. Can not contact any Support guy, so can not get any help..
For me it is a big issue, because i have Millions of Views every month!
You should have received an email and a notification with more info in Creator Studio. Take a look at those resources and note that you can always reapply for the YouTube Partner Program again in 30 days.
