My Clash Of Clans Account Hacked, Please Help Me To Get Back My Account

My Clash of Clans account's Supercell ID, which used to display the user code #9LJVVOCOJ suddenly got reset. To my surprise, even after reaching out to support through three different accounts and emails, I received no response or assistance. What baffles me is that, despite having two-step verification and Supercell ID recovery set up with phone and codes, someone could effortlessly change my account information. It's alarming to discover how easily security can be breached in Clash of Clans. I'm reaching out for help to regain access to my account. Please connect me with someone who can assist in resolving this issue.
