Hello. I'm rather new to this forum myself, so I don't know how much help I can be, but I wanted to say that your post is a little unclear. I think you did not really provide a clear explanation of your situation and of your question.
1. Who are you being sponsored by? Canadian citizen or PR?
2. Under what category? Spouse, partner, parent, child?
3. Has the SA (Sponsor Approval) been received?
Please go to the CIC website (cic.gc.ca) and look up Processing Times: Family Sponsorship.
If the sponsor has been approved, then they are working on the assessment of the main applicant (you). This can take many, many months depending on which processing office. I think PR applications from Afghanistan are being processed in the New Delhi office, and you can find that processing times for New Delhi are:
New Delhi – India 15 MONTHS
So, I don't think there is anything you can do at this point since 15 months have not passed yet for you. But maybe a more senior poster here has a better explanation for you.
