Shady? You signed up for a trial, didn't ready the terms, didn't cancel, and they charged you as they said they would. How is that shady? They did exactly what they said they would.
When you sign up for the free trial, it literally says right there on the checkout page "Total after free trial: ($99.95 x 12 months) $1,199.40". Beyond that, they email you 7 days before the trial ends to warn you.
