I actually did cancel my old credit card but Enscape is threatening collection agency if I don't pay for another year - hard to get out of being held hostage by their auto renewal policy. If you miss your window of opportunity to cancel, they do their best to squeeze every drop of blood they can. Unlike other software where if you don't pay them, it signals an end to your interest in using it, Enscape tries a very different approach
As long as you canceled before the actual renewal date, your CC will back you on your claim - assuming you have documentation. Usually a company bends pretty quickly to CC claims like this. CC companies hold a lot of power in these situations. Good luck to you.
