I only needed a quick, easy survey for one-time event participants and chose to use the free plan. I kept the survey questions within the free guidelines, only to find out that to see all the survey results, I would need to upgrade to an expensive annual plan. There is no option to pay to view only the results of my one-time survey or pay for one month to get what I need and then cancel. The annual plans require pre-payment for an entire year. This is an absolutely deceptive business practice!
