Blue Dart Express — Late delivery of material by AIR

We have booked a parcel dated 26.07.2021vide docket no. [protected] by AIR. Expected date of delivery 28.07.20 but till date the consignment has not been deliver to our client M/s. Kanmur Electronics Pvt. Ltd., Chennai. It was a urgent materials for our client. Due to urgency, we booked the parcel through AIR. If it is not deliver in time then why it is necessary to booked through AIR? If we booked through AIR, Why it would be late and why we paid extra freight for AIR?

Thanks and regards,

Yours truly,
for BINAY OPTO ELECTRONICS PVT.LTD.
