Mini Chat Support Not Responding to Age Verification Issue

I am a 19-year-old user of the Mini Chat application, and my account was restricted and classified as underage about a month ago, even though I am legally an adult. Since then, I have not been able to use the application normally, and I believe I have been incorrectly treated as a minor. I previously attempted to contact Mini Chat support regarding this issue, but I did not receive any response. Unfortunately, I do not remember my account details such as my username or registration information, but I am fully willing to provide any documents or proof required to verify my actual age. I request that my age be properly reviewed and verified, and that the restriction or ban on my account be removed so I can use the application without limitations.
