Garena Free Fire "Using a Modifier" Message

My Free Fire account with UID 702628787 and nickname SK/ANASBoss has been permanently banned. When I try to log in, I see a message saying that the account has been suspended for "Using a modifier." I play on an Android device. At some point I gave my account to a friend, and I do not know exactly what he did on it. I did not use any hacks, cheats, or third‑party modifiers myself, and I did not intend for my account to be used in any unfair way. Because of this, I believe the permanent ban on my account is unfair to me personally. I am very sad and frustrated to lose this account and all my progress. I kindly and urgently request that you please review my case again in detail and investigate the activity on UID 702628787. If any violation was caused by someone else using my account, I ask you to please reconsider the permanent suspension and unban this specific account so that I can continue playing fairly.
