Confort Expert Inc

Must be shark week again. Beware of sharks.
I've been charged $240 for a technician to come and take a photograph, in mid-November while I am without heat. And there is no follow up. Did I just pay for a no service?

Friday night (19-Nov) my house was full of smoke. I found out that my boiler (home heating system) went up in smoke. I had to open up all the windows in the middle of winter to let out the smoke.
I called the next morning (Saturday) to Confort Expert for a service call. They told me that it must be prepaid on my credit card for the service call.
A technician called an hour later and I told him about the scenero. He told me there is nothing he can do and suggested that I call back on Monday to make another arrangement.
About 30 minutes later another technician called and I told him about what the first technician said. He said he was nearby and had to see it. He showed up later, walked down to the basement, opened the casing of the boiler, took a photograph and said that the boiler is finished and there is nothing he can do. He asked me to sign his work order to show that he was there. Then he left.

Three weeks later, my credit card bill showed up and I realized that I was still charged for the call. I called back to the Billing Department and talked to a representative who passed me to her supervisor. He tried very hard to convince me that he is supposed to bill.
I told him that the first technician already told me that there is nothing he could do so why would the second technician come?
He said that the second technician is to tell me that he cannot provide service.
I said I don't need him to tell me, my boiler the size of a microwave has gone up in smoke, I know there is nothing he could do. I was hoping that the technician would suggest that he could call the boiler manufacturer to get a replacement and come back to do the installation.
He replied that calling the manufacturer takes time.
I said why didn't anyone call me back to tell me that Confort Expert is doing that. We are in the middle of winter and I have no heat.
He again said that calling the manufacturer takes time.
I told him since no one called me back, I called the manufacturer myself and got a replacement in 1 week. I had to call another company to have the installation done the following week. So don't tell me that calling the manufacturer takes time. You guys just did not follow up. How can you charge me when you have not provided service. The first technician already told me that he could do nothing, it should have already closed the call and not charge me. There is no reason for the second technician to come.
He said that the second technician had to come to take the serial number so that he could follow up.
I said when I called the manufacturer 4 days later and reported the serial number, he told me nobody called to make a claim. So Confort Expert has taken the money without any follow up.
I was on this call for over 1 hour for the manager to talk to the 2 directors who refused the refund.
