Fedex — Delayed in responding updates and Package has been very delayed for more than 2 months

Hello,

The shipment has been already delayed from more than 2 months and still it hasn't received. I booked the courier on Dec 7th 2022 from INDIA and it is supposed to receive in max 7 days to USA but still. I am trying to contact the fedex team via emails as currently staying in USA they just updated that payment is pending even we have agreed to pay the amount and they said that they forwarded to concern team but still no updates. Kindly please provide the further details as this package is very important for us and it means. I have tried to communicate from all possible ways but FEDEX hasn't gave any updates. Request you to kindly take this on serious note and priority.
