I will call tomorrow to see if you guys have a compatible kit. Just to update you there are no parts for either the cpu cooler or the AM4 kit missing, every part is accounted for. The parts depicted on the AM4 kit's picture show the parts I received (meaning the error is NOT a shipping mixup but the kit listed is not compatible with the cooler). The instructions for the AM4 kit show how to affix the kit to an air cooler, and there is no way to attach the AM4 kit to the liquid cooler.
The issue is that there is nowhere to screw the retention brackets to the cooler, I tried seeing if the included 'AMD' kit that comes with the cooler would allow include some way to attach the AM4 kit however this proved fruitless. I hope you guys have or can get an AM4 bracket for the liquid cooler as I've already installed the cooler into the case, it was a pain (and took ages) and I'd rather not have to send the whole lot back.
