Ecom Express — I had a shipment which was never attempted for delivery

My shipment reached the delivery center on 19th but they didn't attempt the delivery and posted and update saying address and pincode mismatch and asked me to update it again. So I updated my address again and scheduled a reattempt on the next day that was today. Today morning they updated the status as ofd lock without attempting a delivery again. What the hell is wrong with these guys? Other couriers deliver my parcels and packages without any issues. What is wrong with you? I need a resolution asap. My tracking number is: [protected]
