I called the customer instead of knocking a third time
Last year, a lot of customers purchased air cleaning equipment from the HVAC supplier where I work. Some of the folks bought a one-year service contract with the air cleaning machines. The folks that bought a service contract started to have issues about six months after the contract was up. Many of the customers were not properly maintaining the air cleaning equipment. One customer called the repair business and set up an appointment for service on the whole home air purifier. I responded to the service call. The older woman seemed very nice and friendly. She offered me a bottle of water and didn’t bother me at all while I was evaluating the problem. I told the customer exactly what was wrong with the air purifier and I gave her an estimate for the repairs. The woman signed the repair estimate and I started working. I spent almost three hours at the service address. I didn’t finish with the job until after lunch time. I packed up all of my tools and walked out to the truck. I prepared the statement for the customer and I even added a ten percent discount coupon code. I walked back up to the door and I firmly knocked. No one answered the door, so I firmly knocked a second time. I had just left through the front door, and I assumed the customer did not hear me not. I called the customer instead of knocking a third time. The woman answered the phone on the first ring and she told me to go away. She wasn’t going to pay for the repair.
