The worst experience today with comcast tech

My name is Khan and My account number is [Edited: "Personal Information"], I have been a Royal Comcast customer for a decade and love Comcast; I have some businesses in Redmond and Bellevue, and Comcast service is there. I have a complaint today about my home account. I had a horrible experience today; three weeks ago, Cyclon was here, and most homes in the city were out of electricity and internet; one huge tree hit my house, and we have been out of electricity and internet for 3 weeks. I called last week to make an appointment for today, Monday, 12/9/2024, between 2 to 4 pm. I managed my schedule and waited for the technician; my wife and daughter waited just behind the main door, and everyone was on their phones. The room was quiet; suddenly, my phone received a message at 3:47 pm: "Your tech is outside. Please greet him asap." I was there at precisely 3:48 pm, and I saw the guy (Mr. [Edited: "Personal Information"]) backing up his truck; I waved to him, and he stopped the car and came to me, and he said, "I am leaving," I was shocked so I asked him why?, he told me he knocks the door a couple of times, and he is waiting since 10 minutes, He was lying, I knew it. I asked him. I was just behind the main door, and this was not possible. I couldn't hear your knocking, not even my wife and daughter. But he told me I am leaving now. I was distraught; I asked him because you are here, kindly fix my internet. I have been out of internet service for three weeks, but he told me I had been here for 10 minutes, and now I was leaving; he was insulting and unprofessional, which is unacceptable. I am distraught; I called Comcast and complained about this issue, but I am not sure if anyone has taken any action against this issue or not.
