There is nothing you can do, really. You can try and call 1-888-242-2100 (IRCC Call Centre), spend 10-20 min going through the menu, trying to find the right choice or get a hang of a representative (sometimes it ends the call because the queue is very long) and wait for another 30+ min on hold.
Did you give you biometrics during the past 10 years? For visa/work permit/study permit...? If yes, you can send IRCC your old biometrics via webform.
Other than that, you will be told to wait for a call to schedule a biometrics appointment or wait till the offices open.
