You open your email to find an angry, nasty note from a client. Or you pick up the phone, and you hear yelling on the other end. If you have customers, then you’ve experienced an angry one at least a time or two. If you haven’t yet, it’s bound to happen sometime. I’m not trying to be negative here. No matter how much emphasis you place on providing a great customer experience, mistakes and misunderstandings happen, and sometimes, those situations lead to angry customers!
