Express Appliance Repair

I contacted the company to come and fix my water dispenser, which stopped working. I got someone coming in the next day and diagnosed it was the valve not working. He gave me a quote for 500 dollars to change the valve to the water dispenser, I thought it was higher than what I was expecting for sure but still decided to proceed as I like the filtered water from my fridge. They contacted me when they had the part available and scheduled a 2nd visit. When this person came the 2nd time, I was next to him while he was doing the change. After changing the part, the fridge didn't work. It was showing exactly the same issue. He then mentioned that I had a leak in one of the hoses that go from the valve to the actual dispenser, and that the fridge has some "intelligence" to stop the valve from getting the water to the dispenser if it detects a leak. I was unimpressed with his explanation and challenged his argument. I asked him if it was not possible that the hose was what it was the problem from the very beginning, but he kept insisting that the fridge had 2 issues, the valve and the water leak (although I NEVER saw any water coming out from my fridge). When he left, he took with him the old water valve (didn't ask me if I wanted it, which I am usually asked by any technician who comes to replace a part). He did leave the hose he changed though. This left me even more uneasy about the whole situation. The water dispenser was "partially" fixed for a month, after which it stopped working again showing exactly the same symptoms from before. Over the month between the first repair and the 2nd breakdown, I tried to talk to the manager of the technician but every time I called they would tell me to call later because the manager was not around. They never offered to call me back. When the water dispenser stopped working again, I called and requested another technician to come, but they told me it had to be the same person because he "knew" the history of my fridge. When the person came again, he took quite some time to provide his diagnose. This time, according to him, my fridge had the wrong settings for the fridge temperature (which I never changed for sure in the past month) and that it was freezing the water in the hose to the dispenser and his fix was to unclog the hose. I was certainly not happy and even upset and told him that it was very hard for me to believe that my water dispenser had 3 different issues all at the same time that caused it not to work. And that I had serious doubts that the valve was required to be changed. He said that the water dispenser was fixed (3 times) and that I should be "thankful" for the amazing job he had done. And that indeed 3 things were wrong with my fridge (all happening at the same time). I have been trying to contact the company to discuss the situation with no luck. For the above, I would NOT recommend this company.
