One of the biggest challenges that I faced in the last job would be just the fact that I ran into customers who weren't able to diagnose build issues themselves and therefore they would come with a giant complaint. They would have mounds of paper stacked together and they would just be wondering as to what's going on with their entire bill and I would dissect that, I would go into their billing history and then we'd be able to find out where they were at fault, where that may have been a missed bill payment. There's various things that played into that role. However I believe that I was able to do that in an adequate manner and I was able to do that efficiently and accurately and the customer was able to leave knowing that I was able to solve their issues.
