Thank you for the response, although I am sorry to hear that the trouble continues to persist.
Overall, the Verizon biller itself is currently listed as "Healthy" and is not experiencing any known outages or issues.
At this time I would recommend contacting support directly for advanced troubleshooting steps.

Quicken Care has the ability to review the online biller profile and report any issues if necessary.
Thank you,
