I like to handle difficult clients by, first of all, listening. It's very important to listen to what the customer's issues are and definitely need to show compassion and empathy for their issues and do anything that I can to help the issues get resolved. And definitely, if I tell a client that I'm going to call them back or that I need to find another answer, and I call them back, I always call them back. It's very important, I feel, to do what you say. Always follow through. Don't leave. Communication is key, for sure.
