Total fraud! I googled a book, and it appeared to be on playfine.net. I subscribed for the 5-day FREE trial in order to read it, and they assured me that there will be no charges incurred. It turned out that:
1. The book is NOT on playfine.net
2. Without any warning, they will automatically upgrade your account to Premium, which will cost you $34.95.
3. If, however, you try to cancel the Premium update before the end of the 5-day trial (which was my case) - there is a $1 fee for online cancellation. Once again - FEE FOR CANCELLATION! But, wait, you can also cancel for free by either calling them (which in my case would have costed far more than $1, so I didn't even try), or you can email them. The thing is, that you CANNOT send an email - that function doesn't work from the website, and they haven't provided any email address that you can use.
4. The best case scenario: you end up paying the $1 cancellation fee, and that's it. HOWEVER, there is no option to delete your account permanently. So, these cheats have your credit card details, and it appears that there's nothing you can do to END and DELETE everything that relates you to playfine.net.
Dear playfine.net owners,
From the bottom of my heart, I wish you a very quick bankruptcy, and many other unpleasant things.
