I Lost My MLBB Account With 7 Legend Skins to a Hacker

I have been playing Mobile Legends: Bang Bang since 2017 and I own 7 Legend skins, almost all collaboration skins, almost all series skins, almost all Collector and Epic skins, and many other expensive skins as well. Of course, I also own all the Special, Elite, and Basic skins. I also have nearly all of the expensive recalls and the Naruto collaboration tower. I’ve spent a lot of money on this game. Three days ago, my account was hacked by someone else, and of course I contacted their customer service (CS). On the first day, CS instructed me to submit proof like my ID, proof of diamond purchases, and so on. I already sent all of that. However, my issue was not resolved. My account is connected to my three devices: iPhone 15 Pro Max, iPhone 11, and Samsung Tab. The CS also asked me to provide my Moonton account email and password, and instructed me to switch accounts from the iPhone 11 using an account they gave me. But the account they provided was banned, and I couldn’t connect to my own account on my iPhone 11 at all. I could still log in using my iPhone 15 Pro Max and view the history—and the hacker was still actively playing with my account. On the second day, I was instructed to do the same thing with my Samsung Tab, and the same thing happened again. I even tried resetting my iPhone 11 just to be able to enter the game and switch accounts. But when MLBB asked for a verification code to be sent to my email, I never received the code to this day. Now it’s the third day and they’re still responding to me, asking me to log out from my iPhone 15 Pro Max and to change my Moonton account password through them. I complied and gave them the info, but when I asked for the new password, they never responded to my messages up until now. It is very clear that they have neglected me and are not taking any responsibility for this matter. There has been no response at all, let alone any kind of compensation. I really want to sue them, but I don’t know how. I truly feel robbed, harmed, unappreciated, and disappointed with them. I hope this game goes bankrupt as soon as possible!
