During the trail period there is no way to cancel the trail prior to being charged. The instructions on goodle search are incorrect and there is no cancel button. I would stay away from this site, since the trail will cost you $228 and the capabilities of the AI are basic at best.
Update to review. Company did refund money. If you do the trail, make sure you have a cancel button when you go to change plans. If you don't like I did, request to cancel many days prior to the trail end date.
