Although the service was useful, you may stop using it at some point. Be careful with their subscription policies, they will steal your money without any chance to refund and the support will tell you that they will not refund although the subscription was cancelled a day before the charge. My opinion is that this is a fraud. No preliminary notice of charges, no notice of trial period expiration and no chance of getting the money back. I would rather find some other service than the one that tries to charge me in a hidden tricky way, but if you can still try, but then immediately delete your card from the account.
