May be wait for Seller response and have it fixed by seller. At the same time, call or email the courier company to deliver immediately at the mentioned address (don't tell them you bought item etc.. you just tell them that you need to receive a parcel from ..... with courier number/id ....).
Some courier agents will be lazy or take advantage of not delivering to far away places thought your area would be serviceable in their list.
If nothing worked out, still need the item, if you can afford going to courier office, take it. Else leave it and let the pack get returned. Request the seller to ship through India Post again or for refund of your money.
