Blue Sky Duct cleaning Good deal turns into scam Nationwide

Well I had a deal come on through livingsocial and decided to take advantage of it. Blue Sky Duct Cleaning, was offering $50 air duct and dryer cleaning. I scheduled the appointment and 4 weeks later they were here. Well things didn't go well, they first asked for my voucher, then inspected one air duct and inspected the system in the attic. After that I was told that I have mold in my ducts and they can get rid of it with 3 separate chemicals which they wanted to charge me $299 per chemical. then wanted to use a UV light for $399. I declined his offer and the worker got upset.

He proceeded to tell his other workers to go upstairs, which I dont think they were cleaning my dryer vents upstairs. The head man stayed downstairs with his vaccum cleaner, barely cleaned one duct,  got on his phone and texted, packed up his vacuum and workers and left.  I was shocked with awe, and have tried to contact the company. I have left messages with them with no callback. I have contacted living social about the deal and they were able to give me half of my money back in social bucks.  Needless to say this is a fly by night company to get money from people. They are even offering a deal on group on for $45 bucks, same deal and everything. Buyer beware.
