Hello @mac53pan, thanks reaching out and I can assist you with updating your billing address! Can you please send me a private message including the full name as it appears on the account, your full name if (different), the full-service address, the primary phone number attached and the account number?
To send a private message, please click my name "ComcastAmira" then select "Send a Message" on the right side.
@mac53pan, I never received a private message or heard back from you, so I will be locking this thread. Please still send me a private message if you need assistance with updating the billing address on your account. Please create a new Public post if you need assistance with any new issues or concerns. Thanks!
