Trackon Couriers — Complaint regarding not delivery of courier

The trackon courier service initiated the return of the courier without attempting even a single delivery. We are facing a lot of problem since the courier contains MBA books, my exam is from next week. This is highly unprofessional behavior from the courier team. The person who is responsible for courier in my area was very rude, he himself was not aware as to why the courier has been returned without even making a single delivery attempt.
