My PUBG Mobile Account Was Unfairly Banned for One Year Due to Unauthorized UC

I've been a dedicated PUBG Mobile player and have invested so much time and effort into my account (ID: 5347****58). Recently, a large amount of UC was added to my account without my knowledge. I didn't notice it at first, but apparently, my friend loaded it, and I'm unaware of how it was done. This morning, when I logged in, I was shocked to find that my account has been banned for one year due to this UC issue. This is completely unfair! I've never engaged in any fraudulent activities, and now I'm being punished for something I didn't even do. I urgently request that my account be reinstated immediately. PUBG Mobile, please look into this matter and resolve it promptly. I don't deserve to lose all my progress over this misunderstanding.
