Fedex — Customs clearance pending since more than 40 days...2nd reminder

AWB[protected]International Priority Delivery)
I have been waiting for the response of FedEx since December 16th 2021, when the parcel arrived at Bangalore customs. No body at their customs clearance office bother to reply to my mails or answer phone calls. Only their customer care service provides repeated standard line " will get back to you with 24h", but all in vain. Most pathteic customercare, when unable to answer properly, they simply disconnenct the calls.
