My IPV6 prefix delegation seems to have broken again

Thanks for reaching out @rob__jr! We appreciate you for confirming what steps you've already taken. We’ll need to take a closer look at the account. Please send us a direct message with your full name, business name, full address, and last four digits of your account number or full phone number linked to the business account. To send a Direct Message:
 
• Click "Sign In" if necessary 
• Click the "Direct Messaging" icon in the top right corner
• Click the "New message" (pencil and paper) icon 
• The "To:" line prompts you to "Type the name of a person". Instead, type "Comcast Business" there 
• - As you are typing a drop-down list appears. Select "Comcast Business" from that list 
• - An "Comcast Business" graphic replaces the "To:" line 
• Type your message in the text area near the bottom of the window 
• Press Enter to send it

Done!  Thanks for the instructions.
