Amazon India — delivery issue product not delivered

Hi Amazon Team,
I am extremely disappointed with the service experience related to my recent orders.
I had purchased: GM Cuba 3341 Extension Board
Order No.:[protected], placed on 18th Nov, expected delivery 20th Nov. Although the order was marked as delivered in your system, it was not physically delivered. I escalated this through chat on 21st Nov, after which a replacement was initiated.
Replacement Order No.:[protected], expected delivery 22nd Nov. This replacement was also not physically delivered yet marked as delivered in your system. Out of frustration, I contacted customer support. During the call, the executive disconnected midway. When I called again, the next executive transferred me to the Senior Escalation Desk (Ms. Aditi), who responded politely and assured that the issue would be resolved within two days. I was informed that Amazon would recover both packages and deliver the correct product. However, yesterday the delivery executive merely threw a package in the security room and left, and only then I discovered that the product delivered was used, faulty, and not the one I ordered—after I have already been waiting for 7 days for a paid item. Today, when I attempted to escalate this again through chat, the session was abruptly closed without resolving my issue. This level of service is completely unacceptable. I request immediate action to resolve this matter, including recovery of the incorrect product and delivery of a new, unused, and functional item.
