Indian Postal Service Speed Post
Speedpost to Singapore untraceable

I booked a speedpost to singapore EW153313269IN which should reach in a maximum of 7 days and should be raceable on the web. But niether is it traceable on the website and niether has it reached the recipients after 16 days. Above all the Post office officials have been rude and liars in accepting our written complaint. I mailed the customer service team but no reply in 7 days. On calling them up they are asking us to run to every other post office and get information. What is this? even after paying we are getting such a treatment.
