Mr Fireplace

my dealings with Mr. Fireplace were nothing but unpleasant. The individuals that showed up were to change out a simple valve on the fireplace due to it not working properly. Keep in mind that this was a 3 year old condo building/fireplace. According to the manager of Mr.Fireplace the valve was replaced and the igniter busted while they were replacing the valve. They did not notice that until they came back a 2nd time, therefore charging for a 2nd drop in fee. When they finished the work in the afternoon they demanded payment right away, before I could see if it actually worked this time. So when I told them no payment until I see it actually working, they threatened me with a lean on the condo.
Now the part that pissed me off, keep in mind we paid them all ready $600 to change out the valve and fix the fireplace. I get home fireplace still does not work. I called a separate vendor to come check the work that Mr.Fireplace did. Well low and behold the valve was not changed out, they have a date stamped on them when they are produced, mine was still dated 3 years ago. So the new vendor changed out the valve for $400 dollars and it works just fine.
When I confronted the manager at Mr.Fireplace they told me that was impossible. I told him well I have the original valve in my hand and a bill for $400. Since I stilled owed $50 for the igniter and drop in fee. He mentions that if I don't pay the $50 dollars they will place a lean on the house. I asked him why he is not standing behind his work, answer "why should I you already paid me". I told him forget it, I am not paying the $50.
I would not recommend Mr.Fireplace to anyone, better to keep your money and not have a fireplace that works.
