Ooni volt 2 issues - customer support contact/response

All,

Just got a Volt 2 and noticed incredibly loud rattling noise when warming up that definitely does not sound normal. Very disappointing.

I e-mailed ooni support and it's a day and half and there's no response at all. How do they take to respond?

I can't even find a chat button on their website to contact them. Is there any other way at all to contact them? I have been hearing about this supposed great customer service and i am finding hard to even get in touch with them.
