If my credit card gets cancelled, do you cancel my Shell or is there a grace period?

We will attempt to charge your credit card approximately three days prior to the expiration of the account. If the payment fails, we will attempt to charge the card each day until the expiration of the account. In the event that payment is not received, the data on the account will remain for 30 days; therefore, although access to the account will not be available, payment can be made within 30 days in order to retain the information on your account.
