[Resolved]  Blue Dart Express — Overcharged and document not booked under the category for which payment was taken

I had to send my original degree certificate from Kodarma to Kolkata. Executive at Blue Dart office suggested me to book a courier under critical mode and he charged me accordingly. Today my courier got misrouted and when I asked customer care executive he told me that it is not booked under critical mode. I also checked for the cost on online portal of blue dart and found that I have been significantly overcharged. Upon searching on google I have found that there are number of people who have similar complains, While blue dart is advertised as safest courier and our company recommend using blue dart for all of these, I am afraid of consequences.

Note: I have a manual bill also where he has mentioned critical and amount paid.
