How to remove stress if you faced an angry customer in duty timing ?

Hi to all. According to my experience/ intention. I feel that the best way to remove stress from any angry customer in duty timings is to first empathize. It's important that you empathize and understand what your customer is telling you. It's important to have a friendship type of relation with these clients over the call so that they share all the information that they have in their heart. Take the free information that's given and then empathize and then give them hope regarding the issue that they are facing. It's important for you to be customer centric. 

I think the best way to relieve stress during work hours while handling an angry customer would be to find the best solution to the problem. Try talking to your immediate supervisors or managers to provide the customer with what they need. Once the solution is provided, you, the customer, and your managers will be able to relax and will also feel a sense of accomplishment.
