Fedex — KYC unit not clear about the rules and troubling the consumers

I have had a parcel coming from hongkong to bangalore, which reached India on 18th of August 2022 through FedEx. I was asked to submit my kyc related documents. Since the shipper has interchanged the address and consignee name, I was asked to submit a declaration regarding the amendment in the consignee name and shipping address. Since the address was o[censored]niversity's I was also asked to submit a declaration in the letter head for the same since the order was for my personal use (individual) and not for any commercial use by the university. I was asked to submit a govt id, gst certificate o[censored]niversity which i uploaded. Inspite of all this, my docs are being rejected everytime. Each customer suppprt person has no idea what is wrong and thus has their own set of rules. The new mail says that the docs are approved but still not accepted because it is incomplete/ not acc to the custom norms. I have resubmitted the documents n number of times and yet my parcel is still stuck at the customs because the kyc unit is not clear about their rules. Even if the error is from their side, i have been asked to pay demurrage charges. What nonsense is this??
