St Courier — Irrespective behavior

I got a courier from sathyamangalam on Monday[protected]. For my urgent need i went to ST courier office Mogapair west branch. The branch incharge Daniel's response was so arrogant and using local language with irrespective manner. We are using ST courier service frequently. Service is very good. But these type of atrocity people will definitely spoil your service. For His behaviour I have to complaint to police. But initially I want to file a complaint to ST courier. worst service.
