If we cannot process your auto-refill due to a credit card processing issue, we will send an email to the email address we have on file for billing contact. This is the only notification you will receive.
It is important to keep in mind that when your Prepaid balance falls to $0.00, you will not use your service.
Credit cards often stop working - expiration, change of address, etc. Please be sure to select a minimum threshold for your Auto-Refill amount that takes this into consideration to avoid temporary service interruption due to simple credit card issues.
