Hi, I need to know whether I can cancel the account if I purchase the 59 dollars a month scheme.
Yes, you can cancel your account anytime. Although, you should also be aware that all the SoGoSurvey data in the account, including responses and saved reports, will be permanently deleted from their servers and backups. For a minimal charge, SoGoSurvey will let let you freeze your account and store your data. Here is a link to their support page if you need more assistance.
