DTDC Courier & Cargo — b[protected]delayed since 2 months

This is in reference to awb # b58820604. This consignment was sent on 31 oct 2018 and not received till date that is 04 jan 2019. The reason this shipment was sent back was said to be wrong aaddress but the address is correct. The delivery boy didn't even bother to call to confirm the address. The shipment has not yet been received by the store from where it was sent.
I called dtdc several times regarding this but every time they kept telling me that i'll receive a call back which ofcourse i didn't. I tried to talk with the branch manager several times but every time he was on a break.
The address of the office i contacted is 269, ground floor, lahari towers, albert victor road, 1st main, chamrajpet, bangalore - 560018.
