Email or PM them here on the forum (stormcrow or thorwren). Adam and Jenny are often very busy, but when they get to you they will do their utmost to provide good service. Just be patient and persistent and they will come through.
At one time there was a prominent wait disclaimer on the HG site, but now you would have to look for ship times to find it. I understand it can be frustrating for a new hanger not aware they have very little "ready" stock, especially after the black Friday sale, but rest assured your new gear will be worth the wait.
