Restricted Account / Empty Dashboard for Non-Payment (No email received)

Hello Netlify Support,

My original account appears to be restricted or locked due to a payment issue. When I log in, my dashboard is completely empty, and I cannot find any of my projects or the custom domains I purchased directly through Netlify.

I never received an email notification or a support ticket regarding this restriction, so I am completely locked out of managing my assets or updating my payment method.

Could a support engineer please manually look into my restricted account and help me resolve the billing issue so I can regain access to my domains and sites?
