Myntra.com — Complain against the Misbahaviour of delievery boy

My delivery date was 2nd of November, But without any information the delivery boy transfer it to next date, i received a miscall in late evening, once i called that number 2-3 times he picked the call and speak like a road side gangster with attitude no curtsy and ethics in voice your delivery will happen tomorrow i asked from which company, then i only i asked Myntra, he said yes. I asked my delivery date is today, He replied i can’t do this, then for tomorrow between i asked to delivery he said yes, but tomorrow evening around 4 o’clock he came, I asked him that you have change he said no, while i am making the payment he was watching with theft eyes, I slightly cover the door, half close till the place I was standing in front of him, then he left the place, i keep calling him, Where you are going, NO reply and went without handover product in front of me. So unprofessional. Is this the ethics Myntra is maintaining? penalty of One month salary deduction of delivery boy and delivery with priority.
