Discord Suspended My Account Due to a Joke About My Age

While using Discord, I once joked that I was younger than I actually am. Discord must have taken it seriously, as they suspended my account. I emailed them with proof of my age, but the last response I received stated that I didn't meet the age requirement, and now they’ve stopped replying to my emails. Despite providing proof from my ID that I am 15 years old, they still refuse to return my account. I need assistance to resolve this misunderstanding and regain access to my account.
