Fedex — Undelivered shipment and extremely poor customer service

Hi,

I have a package that is sitting in Bangalore and left undelivered. This is the first time I sent a package from the United States with a trust on fedex international priority service. But my experience so far is extremely pathetic, horrible and very much dissatisfied. When I asked for the office phone number of the agent to quickly resolve the issue, they don’t respond at all even after repeated emails. They kept on imposing warehouse charges(I suppose). I am already fed up with this service. Please resolve this issue and get my package delivered asap.
Thank you
