DTDC — DTDC document not delivered

Address:

Bangalore, Karnataka

As per the tracking site, my consignment X13236529 is delivered in the address on May 23rd . I was at home and I haven’t received my document . As per site its delivered to security guard . How can DTDC deliver it to a security or some other personal, without my confirmation? We give Phone number also in the address, so that the delivery boy can call and confirm. This same document has been sent last month and that time courier boy return the document that no one were available at home. That not true someone is always available at my home.. I tried to call local DTDC office but not able to reach then, even I not able to reach customer care. Any way to get my document.
