Delhivery — Shipment not delivered to me and mark as delivered

AWB / TRACKING ID :[protected]

I booked my parcel from securement.in on March 1, 2022, and it was handed by Delhivery courier. On March 3, 2022, at 6:47 p.m. I received a text message stating that my order had been delivered, but I did not receive any orders from Delhivery on that day. I immediately reported this incident to my seller, who also filed a complaint with Shiprocket. I requested POD proof from both Shiprocket and Delhivery, but neither decided to respond.
My seller also requested that provide a proof of delivery. They also not received any reply from you I am absolutely stunned to know and understand that without entering an OTP, Delhivery Agents can mark my parcel as delivered.
Please provide my parcel or refund to my account as I have not received my parcel as I have not received any communication from both of you, it will be assumed that you do not want to resolve my complaint, and I will file a complaint with both companies in the cyber crime department.
