This definitely qualifies as something that only calling in will fix. If you're certain that your emails aren't going into your spam and you aren't receiving the bills. Call *611 and ask them to look into it for you.
Hey Dan! I would also suggest verifying if your notifications settings have been somehow altered in your self-serve account. To do that, log into your self-serve account, go to change address, then click on change bill type/notifications, and then make sure that your "email notifications" are on. You also have the option to receive bill notifications sent directly to your phone! Let us know if it works :)
