WTF?

OK I have to always check my emotions at the door when I get to work; because my job has evolved into 90% sales and 10% customer service. So you know what when a customer came on my line this week and told me that he because we billed him for two months and debited his account he had not eaten in two weeks I had no idea how to proceed because after apologizing several times he kept saying it over and over again. This world has gone haywire and it is too much to handle.
