AirDoctor Review By Frustrating

I ordered my air doctor 1000 online from your site. When I put in the information I received a message that the offer had expired, thinking it a glitch (which it turned out to be) I tried two more times and received same message. Then, I got a notice from my bank that I was paying for three air doctors. I immediately called your customer service and asked to cancel two of them. The person on the phone said she could not do that and went to speak with someone else about it. It turned out that only one air doctor got canceled and I now have to go through the hassle of returning one. The site never acknowledged that my purchase was confirmed or I would not have repeated the process. Poor service and website.
