I enjoy having phone contact with such a diverse group of people. I wish I could develope a business from home where I could generate an adequate salary, speaking with people, without cold calling (sales). Of course irrate customers are the most challenging, but they are also an opportunity to see if you can maintain your professional approach and complete the task before you. If nothing else a challenging customer will keep your skills polished. The this I dislike most about being a csr is, the time constraints that are in place that a csr is being graded on. In some areas of the csr field, it is impossible to give great customer service within these time restrictions, which I feel is a liability in regards to the customer experience.
