Blue Dart Express — Why Delay Caused Beyond Control?

I was trying to reach over[protected] this number which is useless not even a single time it get connected after trying hundred times. And even tried to call the delivery person but he was not picking the call and now status is showing Delay Caused Beyond Control. What is this going with Blue Dart I haven't seen this kind of worst service I get services with multiple other courier service but Blue dart is worst. In terms of Customer support in terms of services. Now I'm not sure whether I'll get my important Parcel or not.
