How to connect to IBKR Phone Support?

I'm trying to contact phone support, but I keep getting stuck in a loop.

When I call, it asks for my account number. After that, I'm prompted to authenticate (or choose support representative authentication). As soon as I complete the authentication, the call disconnects with an automated message telling me to create a support ticket and call back.

Has anyone else experienced this? Is there any way to actually reach a support representative, or is there another contact method that works?

Thanks!
