Same thing happened with me. I called IRCC just a while ago for the status, the agent asked me when was the last time i called IRCC for the update? When i mentioned its more than 6 months ago, he put me on hold for about 7 minutes, came back with the response that he has sent an email to the office to check on the status of the application and that the only status he has right now is the one which is available online.
When i asked him how will i get to-know the revised status after hearing back from the office, the agent advised to call back in a few days or to check the status online. (assuming the email from agent might expedite the process or update the online portal at the least).
