Sorry to hear you've been waiting so long. For us to look into it further, we'd need the screenshot of your channel's monetization page: https://yt.be/help/acmo ? Keep us posted.
Thanks for reaching out. If you haven't heard back yet, this means our team has reviewed your channel & would like to look more closely before taking a final decision. Also, as all the applications are manually being reviewed it does take time. Hope you hear back soon.
