If your card is declined for insufficient funds or is expired during your renewal period, TheraBox may automatically keep trying up to 10 times over the course of 11 days to renew your subscription. If we are still unsuccessful after the 10th try, we may automatically move your subscription renewal to the next month and will repeat the process of renewal again. If your renewal remains unsuccessful, then your subscription may automatically expire or be cancelled. Please ensure your credit card information is up to date to be successfully renewed. TheraBox is not responsible for any overdraft charges from banks or credit cards.
