[Resolved]  Fedex — KYC documents and custom clearance

My sister-in-law had sent a gift item From Hongkong and it's been 3 days that I'm clearing it's KYC documents. the address which is mentioned is of my father's office and now FedEx is asking me for document in the name of office. I have already attach a document where it is mentioned that my father works there but still KYC teams is telling me to upload document in the name of office.
And also about clearance charge why ar theu asking me ₹18347 such a big amount as it is mentioned Gift.
My AWB no. Is[protected]
