We'd like to help. Can you help us with a screenshot of your channel's monetization page: https://goo.gl/1BPKtL ? Appreciate the details.
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!
