Unable to Access Activision Account, Potential Deletion of My Profile

I haven’t logged into my game for two days, and when I tried to log in today, I couldn't access my account. I used my Activision credentials, but it says they are incorrect. Who gave you the right to delete my account? I’ve invested so much time and effort into it, and if all my progress is gone, I’ll consider legal action. This issue needs to be resolved immediately. Please help me regain access to my account—I can’t afford to lose everything I’ve worked for.
