Pretty simple review,
Asked question,
Paid for question all ok,
Unsubscribed
Then charged anyway,
Full refund from paypal not after spending a lot of time on the issue. Enjoy the jpg
Most concerning was the incorrect charge after unsubscribing.
Their system appears to be automated and the lack of follow-through cancelation request appears to be either a result of bad billing procedures or intentional misuse of billing information.
So would avoid,
Probably could have spent the time researching the question in google or a library, but that isn't the point.
