Blue Dart Express — misbehaviour from blue dart delivery guy

Address:

Bangalore, Karnataka, 560102

Hi team,
I was about to receive a delivery from blue dart today (From axis bank). He asked me for a sign. I was checking the delivery number and the paper where he asked me to sign. He got impatient and try to hurry me to sign it without checking. I didi not agree, i said i will check and do it. He took it back and hurled slangs at me. Really disappointed at this kind of behaviour. When i asked if i can get his manager number he ridiculed me and said he himself is the manager.
My address is b/403, salarpuria serenity, hsr layout, bangalore.
