One of the biggest challenges I faced in my last job was that with customer service, sometimes you have those customers who are angry at a situation, that are upset, that are mad, not necessarily at you, but of what's going on. So in this type of situation with customer service, what I like to remember is that the customer is not upset at you, they're not mad at you, they're upset about what's going on, about the situation. So in order to be able to help them, you have to realize that they're not mad at you, and when you realize that, then you try to find ways to help them. And sometimes the customer, even though you're not going to get the solution they want, they don't want to hear no as an answer. Sometimes you have to find other solutions, other ways to help them, and that's what they want to hear, that you're there to help them, that you're going to find a solution for them, and that at the end of the day, if you try your best and you make them feel like you did your best, then they'll be happy with the solution that you come up with.
