India Post — Delay in delivery and no information after calling [protected]

Address: Thrissur, Kerala, 680307

I sent a parcel to Tanzania. The number is EL[protected]IN. These documents are very important for my job and it has to be reached in time. I called customer care [protected], they are so lazy to pick and if they pick they wont speak and hang up the phone. I feel regret of sending documents through india post office. You have to think that you people are playing with a good career and future of the people.
