Shadowfax - Delayed delivery

Date ** january , Dombivli nilje
Hello I have to file complaint regarding SHADOWFAX DELIVERY AGENT named sanjay and his contact number **********.
Person behaviour is not nice . He behaves as if he is the owner of shadowfax . Whenever he is appointed for delivery he never comes on the day appointment. Everytime he delays my parcel . Also he don't receive calls
For pickup and delivery also he always delay *-* days .
This thing is happened with me *-* times . Also I called him once and asked at what time will you come for pickup so he replied - "I will come whenever I want" . On **th January I placed order on nykaa and on ** it was supposed to be delivered. I got message from shadowfax and shared delivery agent number ..
So in evening on ** january I called the delivery person named sanjay he didn't answer so after a while I called again still not answered again I called *-* times he rejected call
Then I received message from shadowfax that delivery is not possible today it will be rescheduled to ** january ..
Then today on ** january I called the person ** times he is rejecting my calls and not answering.
Also once at late night *:** pm he was attempting delivery so I denied to get my parcel at that time so he started arguing with me on call .. and said company allows us to deliver late night .
And from then his behaviour is like this with me ..
Since then he never delivers my parcel on time .
