My trinked disappeared
In-game requests won’t get you a response, it’s used more of a bug/user reporting system.
You need to make a support ticket. In the top right of this page: Services -> Support -> Submit a ticket. You’ll get an email confirmation and CS should get in touch in 3 days or so.
Edit: Have you checked your other characters? And a minimized bank tab is also an embarrassingly common reason for “disappearances”
