DTDC Courier & Cargo — Courier CN No. M44216913 not delivered

Address:	400077
Website:	www.dtdc.in

I had sent a courier CN No. M44216913 from Mumbai on 20 January, 2017. I was informed that courier will be delivered to its destination Amritsar within 2-3 days.
As per the tracking history available on the website, courier reached Chandigarh on 21 January, 2017 but no update after that.

I called so many times on Chandigarh Customer Care but they just say that they have sent the courier, it should have reached Amritsar branch. But Amritsar branch says that the courier has not reached there.

None of the customer care executives is answering the issue. Neither they are trying to figure out the courier status.
