Konami ID Security Issue - Unknown Logins Accessing My Account

I am having a serious security problem with my Konami ID account. I had previously given my account details to someone I do not personally know, and now I can see that there are monthly logins and activity on my account that do not belong to me. Today I realized that these unknown logins are still continuing and this makes me feel that my account is not safe. After noticing this situation, I contacted Konami support and followed the instructions they provided. However, the steps they suggested did not solve the issue, and the unknown logins and access concerns remain. I request your help to completely secure my account. I want to recover and remove my account and remove all unknown logins and access, and I want you to ensure that only I can use this Konami ID from now on. I ask you to review my case urgently and take the necessary actions to protect my account and information.
