How to unblock iCloud account?

Hi,

I have an icloud account and upon logging in my account on my iphone 6. I am getting an error that says "You can't sign in because your account was disabled for security reasons. To enable your account, reset your password at https://iforgot.apple.com"

Then I will go to the website https://iforgot.apple.com/then I will get an error that says

No Apple ID Found.

I even tried the reset password method at https://iforgot.apple.com/password/verify/appleid?returnURL=https://appleid.appl e.com&app_id=93&language=US-EN but still no avail it says

No Apple ID Found.
