If its been 4 days you can honestly ask them again. There is probably a backlog right now.
Thats not an excuse for them not telling you solid information though.
You havent gotten it, or it hasnt been sent out yet?
It sounds like a great question for Cryorig's customer support, they should be able to tell you specifically when your bracket should be coming.
I contacted their support and they just replied "We have confirmed it by our system that your AM4 Kit will be shipped out these days, sorry for asking you waiting such a long time." That was 4 days ago

Is there any other place where you can get the bracket? I had no luck finding it on amazon or newegg. Might just buy one because I don't have the time to wait around.
