Mobile Legends Account Stolen - Customer Support Fails to Verify Ownership

Someone has taken control of my Mobile Legends Bang Bang account! I reached out to customer support, but they insist that they are unable to confirm my ownership. I have all the necessary documentation, but unfortunately, it is insufficient. Someone has taken control of my account and is causing trouble by insulting my friends and stealing all my Diamonds. I have the bills for the diamonds! Can someone from the Mobile Legends team please assist me?
