This is a clear example of a scam that is often perpetrated by companies using the Free Trial Subscription Model. In this case, PDFSimpli offered a low-cost trial period, hoping that the customer would forget to cancel and then charged them for a monthly subscription without their consent. While PDFSimpli's terms and conditions state that customers will be automatically enrolled in a monthly subscription, but how many of us when need some service and when we searching for the best one think about this unfair problem which we can get later? Whats the problem to sent email or two before the end of that scam trial period?.
