Contact eBay by phone and ask them to remove it, I am pretty sure the rules say that feedback can be removed if the buyer lodges a dispute with Paypal and it is resolved with no ruling against the seller.  INR means NOT received, if the case was closed because the item was received (however long it took), you only need to point eBay to the tracking and show that you posted the same day and they should agree to remove the feedback, the resulting defect and any low stars as well.
