Apple Developer certificate Revoke

I have received email about your development certificate has been revoked, but couldn't identify who did that, due to this revocation one of our enterprise application stopped working. So posting here to seek some suggestion on following

1.) Identification of Revoking Party: Though I have already raised a support ticket to Apple still waiting for their reply. Is it possible for Apple to send logs or account activity logs that from which account or who did the revocation?

2.) How much does Apple take to reply to the support tickets.

3.) No one else received email in my development team. Is it because the certificate which I created is revoked that's the reason only I have received email?

4.) May I know what are the other scenarios that certificate can be revoked other than a human error?

5.) Is there a way for us to internally monitor activity within our developer account, such as identifying who has been actively logged in and updating certificates?
