Hello @LastPass User,
Welcome to the LastPass Community!
I apologize for any inconveniences you have experience with our support channels. For security we cannot resolve any billing issues through the community since it's a public environment. I am not able to see any recent case created about your request to update your billing information; however, we will be happy to help you. You can open a case, request a call or start a chat by going here: https://support.lastpass.com/s/contact-us and we will be happy to help you with your request.
Kind Regards,
Alejandra
LastPass Support
