One of my courier has been sent from Mumbai on Monday 6-8-2018, to banglore but till Friday I have not received the same. Friday morning around 9.40 AM I called the person regarding the status he said call after 12.00. when we call after 12.00 Pm he said call after half n hour ([protected]).
We checked online status it was in Rajaji nagar branch when we called there he said we will call you after 10-15 mins, but after waiting for 30 mints when we again call him he is again replied to call after 30 mints. On upon that when we asked for his name (which he said Dilip) he said complaint karana hai to kar do.

I don't know why we are paying money to this service.
