DTDC Courier & Cargo — delivery to an unknown receiver

Address:

Pune, Maharashtra, 411007

My consignment dated 15th march was to be sent to a certain adress within pune and dtdc delivered it to a watchman of a building that did not even have the given floor number under an assumption that a few other unknown people were the owners of that item. It was a costly item and its loss wouldve costed me a lot. I had to personally go and retrieve the it from the recevivers. How can i trust dtdc after this
