I am one of many people whose Discord accounts got falsely disabled for being underage. I have seen a lot of people saying that Discord support ghosts them on purpose, but that's just not true. Discord is a huge company with a lot of users and a lot of daily requests. The support is overwhelmed, but I promise you, they will get to you. Even though they took under a week to respond to my age update, they did the job. Overall a smooth process.
