I received a replay sooner than I thought, I submitted my question April 2 (Monday), received a replay from an IRC agent on April 4 (Wednesday)Your case is different from Conaider's. The OP didn't receive AoR so there is no chance for him/her to correct the info online. Also, the application signoff date is more than 3 months back which automatically deems the application as rejected.
In your case, I could see you already received your AoR. So, the chance of getting the application returned back is very low. Use the IRCC webform link (below) to send them the corrected info:
"We verified the information you provided and have forwarded it to the responsible office.They will contact you if further information is required or if a decision is made on your application. We hope the information provided is helpful in assisting you with your enquiry."
