Dtdc Courier — Shipment not delivered - and wrongly updated at dtdc office

Address:

Raipur, Chhattisgarh

Hi,

I have send my courier (RAKHI) through DTDC courier with CN no- M23647471 & M23647532 on 22 Aug-2015.
When I asked in the DTDC booking center they told me that my shipment was delivered on 27 Aug-2015 and he gave me his courier boy mobile nos.

But when I asked to my relatives that whether the courier was received they denied, then after I regularly called on mobile of courier boy, but there was no reply and they didnot answered my call.

WHY they have cheated me?
They have misguided me and they are fraud/

Today they are saying that, the shipment should be collected from office they will not deliver.
WHY?
DTDC has very poor service and they are fraud.
