Enviro Flex Pack review for MAG: Form Builder

I don't get what the hype is... upon setting up the forms I encountered so many difficulties - 1. all of my answered checkboxes are not showing in submissions 2. did not receive email upon checking and entering admin configure email 3. there's no submission complete message. all my answers were erased after clicking "Submit". There should be a thank you message afterward. Spoke to cs but they have a hard time understanding me just keep repeating the same thing... So disappointed and a waste of time.
