Entrprise Account Enrolment 'Under Review' for longer than 1 year. What can we do?

As title says, our Enterprise Account has been 'Under Review' for over one year.


Every email we send gets the same response: 'We checked the status of your enrolment and confirmed that it is still under review. I apologize for the inconvenience, but we do not have any additional information at this time.'


Our next step will be to contact the call center to try to find out why this is taking such a long time. Other than that, is there anything else that we can do to get more information on this? Are there any other communication channels we can use to try and resolve this?


Thank you for the assistance.
