Fedex — Never contacted about package customs fees and now I'm told the package has been confiscated by Fedex

I sent the Package (tracking number[protected] from Jersey City, USA to Kolkata, India in September. It was supposed to be delivered in 4 days, and I paid a lot of money to ensure that.

All I asked was that the recipient not be charged the customs fees, and it be posted to my account. Today, I find out that the package has been confiscated by Customs after they gave a deadline till November 1st to post the payment. However, I have not been contacted about the payment even though they have my phone number and email address (a fact I confirmed with a consumer service representative named Kevin at Location ID SALRC). I am now being asked to file a claim with the Revenue department (who can't help me until January), however, the package, which was meant for my parents can apparently neither be returned to me nor sent to my parents. If it could not have been delivered, could it not be returned to me at least? Why was I not contacted, and then told that effectively, it's a lost package now?

Further, when I asked Kevin to send me an email record of the conversation for my records (since clearly this is a case that will need to be escalated), he said he cannot do that.

I would like to file a formal complaint about the handling of the consignment.
