India Post — document sent from kolkata to canada via speed post (india post) stuck in canada customs with no update for last 10 days

I had sent a speed post via india post (Charges - rs. 1392) from kolkata (Park street po) to canada (Toronto) - wes canada. It was booked on 16th dec from park street po and supposedly sent on 20th dec. But after that i have not got any updates regarding this. It looks like to be stuck in customs because canada post have not received it, they confirmed.

I called india post and told them this issue & they could not help me, did not care to bother. For speed post, it is written they will reach by 8 to 9 days. This is an important document & needs to reach wes canada as soon as possible. Please help me with this by forwarding this serious complaint to india post so that they take this issue on priority.
