Describe a recent situation when you had to handle an angry customer."

I just keep calm and handle the anger by responding appropriately to the anger with minimal verbal. Provide the professional answer with a professional tone. And at the end of the conversation, asking customer with question like "Are you feel better now mam,sir?"

I try to talk her nicely like to caught their weakness until i found it then make it this way to be calm till they make smile and to be sure that nothings happened
