Delhivery — Cancelled my parcel without contacting me

I was supposed to receive my parcel on 14th April. When I checked the status of my parcel on tracking page it showed that our executive is out for delivery but I was not contacted by anyone on that day. When I checked it again on tracking page it showed that your delivery is rescheduled as our executive was not able to reach you. Same thing happened for the next two days. It showed that our Delhivery executive was out for delivery but then no one contacted me. On 16th April when I tracked my parcel again it showed Delivery cancelled as our Delhivery executive was not able to reach you.
Delhivery executive is not contacting me. Without contacting me Delhivery Courier Company is cancelling my order. My address and my mobile number is provided to the company even then I have not been contacted by the company. I have already raised 2 tickets regarding this issue but did not get any response till now.
I want my parcel to be delivered to me on my address as soon as possible.
