Package number:[protected]
This is the worst courier service i have ever come across. I was suppose to receive a package from Siliguri to Bangalore which was sent by speed post and it shows that it is in Kolkata when I tried tracking it online and the number suggested was [protected]. When i call this number there is a very rude lady on the other end who says that the courier is not there. I told her that I could see that they have received the she said "Kaha kaha se mil jata hai number" and hung up i called her again she received the call and just left the phone lying on the table. Such atrocious service. It has already been 8 days and i still do not have my package. Please help

None of the numbers below work, and these numbers are on their official site.
