Hey Vortex 4D,
Have you recently created a new Call of Duty account or changed the email address associated with your CoD account? Can you please let us know what console you play on? What is your gamertag/ psn id and what is your clan name?
I have a similar problem: I play on PS4. My psn ID is ALEDRIVE90 and my clan name is ThePatriots4. And I haven't change my e-mail address. I was the commander of my clan, but on 27th of January, when I signed in, I wasn't a member of my clan anymore. Then I asked my clan members to let me join the clan again. From that moment the comander on the app is Top Secret, instead in the game I result comander and soldier at the same time, even if just the soldier profile works. For these reasons no one can promote any of the members and we have access denied for the Diamond Division!
What should I do? How Can I fix it?
