Overnite Express — no further details about courier's reaching to destination

Address:

Belgaum, Karnataka, 590010

A courier containing books was sent from Kekri (in Rajasthan) to Belgaum (in Karnataka) via the service of Overnite Express on 12th June 2019. On web tracking, it is showing to be dispatched to Belgaum for more than 10 days. I contacted customer care by email and call but didn't receive any good response. I didn't receive any mail. On calling the customer service in Bangalore, it was asked to me to call on the number of the concerned person in Belgaum office provided by the customer service. That concerned person's contact number is debarred from incoming calls which I got to know after trying to contact. Even after that, I tried to contact the same number of customer service in Bangalore. I was asked to share the AWB number via SMS which I did. Still didn't receive any response. I called again and messaged to at least get the address of their office here in Belgaum but still no reply.
