Delhivery — No delivery made

My product was out for delivery on 1st of november and i got an call from delivery executive to deliver but today is 7th and my product was not delivered yet. The Delhivery executive are the biggest liars they are rescheduling delivery without asking me and writing consignee not available. I have ordered many products online but the worst experience is with Delhivery. Now i am have to make a return request and ask for refund bcz i lose hope in delivery. I have made many complaints but no positive response. In future i dont want to be part of Delhivery.
