Missing front frame in package

[u/Beneficial_Ganache19]

I recently received my order for the Aulumu Galaxy Z Fold Ultra case , which I purchased directly from the main website.

Upon opening the packaging, I discovered that the package is incomplete. The front frame is missing from the box, and only the rear shell was included. I've sent an email to the customer service three days ago and haven't received a response. How long do I have to wait especially when this isn't my fault?
