We'd like to know more, Sachin! Are you able to share the screenshot of the monetization page from Creator Studio: https://goo.gl/ySjhEs ? We'll take a look.
If you've been waiting that long, your channel had a first review but we didn't come to a clear decision, so extra effort & resources are going into more reviews. Creator Studio doesn't show this, so it's confusing & looks like you haven't been reviewed. Hope you hear back soon!
