DTDC Courier & Cargo — Not delivered parcel

Am writing this complement for not attending the delivery by the delivery personnel and writing in the status "receiver refused delivery" via e-mail. My shipment awb/ consignment number is V62525933
But receiver has not refused the shipment (I confirmed with them) and now when i m tracking this shipment on dtdc website it is showing not delivered.
I called various dtdc offices in raipur, each of them further gave another number to call and finally the last number[protected] and 62) i got, is always busy.
They should try re-delivery.
I am really hurt with the service of the dtdc. I here request you to do the needful in this matter.
