DTDC Courier & Cargo — Product not delivered to me but they mentioned delivered in tracking details

My tracking is K39350702. It is a costly item. They updated the tracking that my product is delivered but no one called me or texted me or came to deliver the product. Now after calling their customer care says it is delivered to family member with name SR(no proper name) with a contact number which on calling says invalid. Where is my parcel i am not getting any idea.. the customer care is so rude. How can they give it to anyone without verifying on the number provided? Without verifying with ne how does they confirm who is my family member or not? Or should they even deliver it to that person? I sense some fraud here. They might not have delivered at all . They are making up stories. Please help me get this product. This is really a very costly one and cant afford to lose this.
