Just to confirm, was your channel monetized earlier and was demonetized then, or was it the first time you applied and were rejected? Also, please share a screenshot of what you’re seeing on this page: https://goo.gl/297Xrv ? Keep us posted.
This means our review team has not come to a clear decision during the initial review, so we’re putting extra effort and resources into reviewing your channel multiple times before making a final decision. Hope you hear back soon.
