Fedex — Package Customs and taxes amount

This is in link to the other complaint i made- https://www.consumercomplaints.in/fedex-package-not-delivered-for-over-a-month-n...⇄
i still did not receive the package, it is in the destination location but not yet delivered to the mentioned address. The Customs duty and tax charge was estimated for 145276 INR which is absurd, when we contacted them fedex said they already paid amount to customs and we have to pay fedex and only then it will be delivered. Paying that much amount is unreasonable and when we try to contact they just pass around to different sections or put on hold even customs India is not helping. this is huge pain for us to pay that much amount which is almost equal to the value of belonging that was sent, this is getting out of hand i'll never be willing to send any package with fedex any more. i dont know where the issue either with fedex or bangalore airport staff or customs i'll never use fedex services ever again
