Blue Dart Express — delayed service

Dear blue dart services,
It is emminent that your services can't be trusted in the recent light of events, a parcel from Amazon was to be delivered to us on 16th of August by you. The parcel is still not delivered, the excuse given by you being we can't deliver on Saturday/Sunday and that the parcel is too big.
Talk about a lame excuse. If the parcel is soo big, and your services can't handle it, i would recommend you to bot take such requests by yourself and let some other responsible and capable institution handle it.
We would like to get the consignment delivered as soon as possible
Such behavior is highly condemnable..
