If you have been told already that the next step is going to be from IRCC Delhi, why don't you raise a webform there?Just a thought
They are not good at giving any information over calls and I believe they only accept mails or webform issues.
By the way, 3 years since marriage too. It Sucks!
On call Delhi ircc not available. Sent multiple webforms and emails to Delhi ircc too. No luck soo far
