Fedex — clearance delay at delhi

[protected] this is my tracking number my shipment is from bangladesh to india; it's a gift. The scheduled delivery date was on 26 aug 2017 and today is 14 sept 2017 nearly 20 days; since from 20 days am waiting for my package daily i need to call fedex and the response will be wait for your package our agent is trying to retrieve your package and we have written an expertise email and their is no update regarding they say and shut the call saying we cannot tell you delivery date as per now there are many backlogs under custom clearance if i ask further they asked me to complain @fedex india my question is what customer service will do? After paying lot of money on fedex services we get this reward. I don't understand whether fedex people are trying or not. My shipment was a international priority. My goodness and still stuck in customs next time i need to rethink to make a shipment with fedex. I personally feel my package is been completely neglected and i demand fedex to deliver my package as soon as possible at my doorstep. For which i shall be thankful later; as per now am a sufferer.
