Hot Tub Repair

"We accepted the job when the customer contacted us and told us that her breaker was tripping. We told her that we would be at her house Friday morning between 9-10am. We arrived at approx 9:15am. We went into the backyard and found that not only was the breaker tripped but the spa was almost empty. It was also noted that the service panel of her spa had already been removed. I used her hose and filled her spa which took about 30mins. After spa was filled I began an inspection of the spa components. Since the customer had not yet come outside I went to my truck to call her. She did not answer after 3 attempts. She came out on porch and I asked her why the spa was empty. Her reply was "Who are you?" I said I'm from Hot Tub Repair. She then said "Oh, my other guy came yesterday, the spa is fine now." I asked her if she called our office to cancel and she said no. I went to the spa, got my tools and put the side panel back against the spa as it was when I arrived. I then left and did not charge her for the time we spent there. We always ask customers to please call us if they need to cancel because we have busy and tight schedules and other customers waiting. Customer did call me but I was on the phone speaking with the next customer on that day's list. She left a vulgar filled message and I felt it was best that I didn't return her call after listening to the rude, vulgar filled message. I left the spa just as I found it with the exception of filling it up for her which she did not even know it was empty. She told me it was all set and working. How did she know that the side panels weren't off of the spa if she didn't even know that the spa was empty?? All we ask is that customers call us if they want to cancel or re-schedule. We understand that things come up and situations change but at least call us so we don't drive 22 miles just to be called names and have a bad review written about us. We do apologize if there was any misunderstanding between us and you."
