Let them explain the issue and show that you are engaged and empathetic. Often, customers just want to feel heard and understood. 3. Apologize sincerely: Even if you believe the customer is in the wrong, it is important to apologize for any inconvenience or frustration they may have experienced. A sincere apology can go a long way in diffusing the situation and can help to rebuild trust with the customer. 4. Offer solutions: Once you have listened to the customer's concerns and apologized, it is time to offer solutions.
