Try every way possible... first call the call center there. If they dont help you, use the IRCC webform online. Go to the IRCC webform, and it will ask you if your Application is being processed outside Canada. Even though it is being processed in Delhi, say NO to this question. Then you get a webform for IRCC canada. If you say YES it will direct you to the Delhi webform but you need to contact CIC canada about this as it is urgent. So click NO and then under 'type of application' click SPONSORSHIP - SPOUSE OUTSIDE CANADA. If you contact delhi they take a long time to reply. CIC canada usually replies faster. Hope this works for you. If all fails, go to the embassy there.
