Top Line Clean Air

I hired this company, which I thought was a local company to clean my air ducts and furnace. I was offered a special price of 249 dollars, however when they showed up, it was not a local business, but a couple from Ontario. I decided to go ahead with the cleaning regardless how I felt about being deceived. Once they started, the guy I was dealing with told me that I had to spend over 600 to do everything, they had already cut a hole in my furnace ducts so I was reluctant to say no. I felt like I was held hostage to get the job done unless I agreed to spend more than double what was initially quoted. NEVER HIRE THESE PEOPLE!
