I had evaluated several CMS-1500 paper claim software packages and went with Medical Form Software based on it's ease of use. The one concern I had with some of these software packages was if my printer was compatible with the software package. When I called this company to verify printing issues, the person who answered said if it didn't work, I would get a refund. This company doesn't send you an actual CD to load, but sends you a link to download the software. After several attempts, the software did not work. I found this odd since the trial version worked well. I asked Medical Form Software to send me the actual CD to load the software or to credit my account since I was having problems getting the software to work and they were not finding any resolution to get the software to work. The merchant never got back to me nor responded to my e-mail request regarding credit. I made several attempts to call and all I got was a never ending phone ring. Not even an answering machine. That led me to believe that something was fishy on the other end. I immediately contacted my credit card company to dispute the charge which they were unable to help me with stating the merchant disputed the charge back as "no proof of return was provided." How can I return back a link to the merchant that doesn't even work? I then contacted the Florida Consumer Department and the merchant refused to cooperate. In short, do not make a software purchase over the internet unless you get the physical CD in hand.
