Unable to Access My Call of Duty Account After Logging Out on PC

I recently logged out of my Call of Duty account on PC, and now I can’t log back in, either on PC or mobile. Despite knowing my email and password are correct, it keeps saying they're wrong. My account is still active, but I can't access it. I reached out to the support team via email, but received no response or solution. Has anyone else experienced this issue and found a way to resolve it? I'm frustrated with the lack of support and just want to get back into my account. Any help would be appreciated.
