India Post — when will I receive my courier stuck in dimc

Address:

Hoshiarpur, punjab, india

Hi,
There are my 2 packages which were courier on 3rd march 2020 and since then they have not been delivered to me here in canada. Since then the tracking is showing they are stuck in dimc. They are very important and i need them. Due to lockdown if it is possible to return them to the sender so i can get it later once lockdown is over because i have very important documents in it and want them to be secure. If not then there is any procedure for address change to deliver to destination address because the reciever address has been changed.
Please assist because i am really worried now and need those. This is social page so will provide tracking if there is email provide for more details
Thank you.
