Harry, the plumber, was very personable, seemed to have a very thorough knowledge of plumbing tech. He provided a lot of information and was very good about answering my questions. On the other hand, (I spoke to two different customer service persons prior to his visit.), the first female nearly caused me to look elsewhere for service, due to her approach toward me. (This is why I cannot give an Excellent rating in the survey.) The one that rescheduled my appointment was great! She was top notch! Since I have worked in sales and customer service for Many years, I consider I am a good judge of how to appropriately interact with customers and potential customers or clients.
