Moniker.com shuts down startup without warning

Moniker has shut down our website https://www.analog.com.ai without any warning. This stems from a WHOIS email update 15 days ago. Their system failed to send the verification email, and now that the domain is suspended, that email is unavailable.

Their support is not helping, and our business has now been offline for 4 days and counting.

Any help would be appreciated.
