Fedex — Delay in Receipt of Documents ( more than one month)

Address:

231,23rd Flr, Dhawalgiri Bldg, Megh Malar Complex, Yashodham Goregaon East Mumbai 400063

Airway no.[protected]
It has been a month since my son sent courier containing documents from by my son Raghu Venkatesh, San Jose, CA (Power of Attorney for property purchase) by Fedex. We have still not received the same at Mumbai ( addressed to T K Venkatesh Kumar, Mumbai). While tracking the courier, we find that it is stuck in custom clearance. Since it has only documents and a duppatta (used one), I cant understand why it has been stuck with Customs for a month. Is there any way to reach out to Customs ( email or contact number) to explain this. This is a very important courier and I am suffering financial loss due delay in completing legal documentation for a property purchase to non receipt of Power of Attorney.

Unfortunately no one has contacted or reached out to me from Fedex. I dont expect such service from FEDEX (of all couriers in the World you are supposed to be best).
Let me hasten to add that KYC was sought and completed long ago.

Please intervene and address my genuine complaint
