Same thing happened to me I received call today . I ask my consultant about these and he suggested me to bring my spouse with me and request them to take biometric for both because as file number is same.I got my call now. AOR May-23 and BIL July-15. Appointment Oct-26 in Mississauga office.
I requested them to book appointment for my spouse as well. but they didn't do it as her name is not in the list they received from IRCC. Waiting for her call.
if you call ircc please let me know what they reply.
