Item booked on 3rd october and now they are showing "delay caused beyond control", other courier services haven't any issue regarding delivery load so what is problem regarding blue dart. And if they can't deliver a item then why the book the item form its source. Isn't a cheating? Some one is paying you to deliver it by paying you charges and after taking the charges now you saying that i am not able to deliver it. Blue dart should banned.
