Ecom Express — ECOM EXPress - Package not delivered

My package is out for delivery from 27th March, 2021. Delivery guy called and asked for route on 27 march and told that he will deliver on 28 th march. But delivery guy updated the status as " Consignee requested for future delivery".
I missed to pick the call from delivery person on 29 th march and i requested for next day delivery. on 30th march i got call from ecom express but it was a blank call and nobody spoke but updated the status as "customer not available" whereas i was available and answered the call. i raised complaint and requested for delivery again.on 31st march again got call again it was a blank call and i recorded the call for complaint purpose. status has been updated as "Shipment un-delivered Shipment attempted - Customer refused to accept" . request you to deliver the package as early as possible.
