FedEx - deficiency of service leading to mental harassment and financial loss

Fedex carried international shipment awb ************ on ** September ****. It did not get delivered until more than * months and a trail of follow-ups took place between me and FedEx executives but in vain. Ultimately the shipment was written off for disposal. Without any action on the part of FedEx, I myself visited Customs at igi Airport New Delhi on ** February and met the officials there who inquired me on my imported product detail and just asked me to write a written declaration that my product does not need noc from the additional drug controller. After * days, that is, on ** February I got my shipment delivered. If FedEx executives would have communicated the same to me with so much ease I would not have to undergo business loss for more than five months and additionally the mental turbulence could have been saved for * months at a stretch. FedEx exhibited “deficiency of service” by failing to coordinate between the Customs and the customer to get the shipment delivered and displaying an attitude of “let go” on the shipment.
Mental Suffering: Being a layman, we would do and provide everything that FedEx Customer Support would ask us for, but when FedEx displayed the callous attitude being at the receiving end I felt sheer helpless, frustrated, and cheated. Day in and day out, I would research and re-research on internet if I imported a prohibited goods of some sort, contact various related people, follow up FedEx, arrange for the stuck fund from moneylender, not knowing if at all the shipment would be released or not, not knowing if it will be released then on which date....a never-ending list of agony that can only be understood if someone is going through this.
Financial Harm: Being a small re-seller, Rs. ***** worth of shipment loss can be recovered only after selling off * such shipments. Moreover, I also had to bear the below:
*. Gross sale loss due to being out of stock for ** days = Rs. *****.
*. Up and above, I had to order for the *nd invoice worth Rs. *****.
*. Net loss incurred Rs. (*****+*****) less Rs. ***** (sale proceed received on February ****)=Rs. *****.
Misfortune: Had FedEx been proactive with customer’s issue such an incident could have been contained and cut off.
