I needed to send a quiz to event attendees. And I needed for them to be able to retake the quiz if they failed. Survey monkey says re-take is part of the paid package. So I paid to upgrade and then discovered the feature was NOT AVAILABLE. Contacted them immediately - they ignored my first email. Contacted them a second time and refused to refund the payment, despite the fact they falsely sold me a feature. Lime survey is much better as a survey tool, and for quizzes I found an execllent tool called FlexiQuiz that does exactly what SurveyMonkey claimed to do but doesn't - with a free trial to prove this. Avoid this company.
