Shipping Issue, No Response from support tickets

I ordered on the 23rd of January, and tracking info says UPS still hasn’t received the package. My support tickets go unanswered, I’ve only gotten the copy/paste responses about heatbed cable issue. How do I get actual support for my purchase? Is there a phone number to call? Is a chargeback my only recourse? I don’t want to do that, I want the printer, but I am at a loss here and out 750 dollars. Would appreciate any insight anyone can offer. Thank you.

Right now is Chinese New Year. I’m afraid you’ll have to wait until February 21 before you get a response.
There is no phone number available you can call.
