DTDC — product returned without any intimation

Address:

Thiruvananthapuram, Kerala, 695584

Dtdc tracking no z57908303. On[protected] website showed that "receiver not present". But nobody attempted to deliver. There was my representative on the address for the whole day. They haven't called me or message. On the same day i've mailed my query to [protected]@dtdc.com followed by 4 subsequent mails. No single reply from dtdc and they simply returned product.
