Free Fire Facebook UID Permanently Suspended For Abnormal Activity

My Free Fire account, which is linked to Facebook and has UID 477151042 and nickname “KHAIRUL”, has been permanently banned. This account is very old, I have been using it for a long time and I have spent a lot of money on top ups and skins. Now, because of the ban, all of that money and all my skins feel wasted. When I try to log in, I see a suspension message on the screen saying that there has been “abnormal activity” on my account and that it has been suspended permanently. I really want my account back because I have played for a long time and built this account with a lot of effort and purchases. I kindly request that my Free Fire account linked with Facebook and UID 477151042 be checked in detail, that the ban be removed if possible, and that my access to my old account and all my items be restored.
