We’re so sorry but due to the payment company’s system, we can’t reactivate the subscription that’s already been canceled. So, we would appreciate it if you could start a new one on our pricing page
To find out the reason for the payment failure, please contact PayPal or your card issuer directly whether you made payment as a guest or not. Thank you for your understanding and patience. 

For your information, if you purchased as a guest, a card problem could be the most likely cause because non-members can’t change the card information used for payment and they can’t have a PayPal balance. 

If you purchased with your PayPal account, card expiration or the insufficient balance may be the reason. Since it is an overseas transaction, rejection by the card issuer due to being recognized as fraud could also be a reason.
