This morning (May 15th) I finally received an email from Mammoth. They took accountability for the fault in the drilling process. There is a new enclosure on the way, no extra charge, plus I get to keep the one with the wrong drill holes. The new box should also be here by Friday (1st class ship). So, after an email and 2 Facebook posts, the issue seems to be getting a lot better. Hope all goes well for the rest of yous. And if they fumble, hopefully they can recover like they did for me.
On another note, I just bought a bunch of drill gear to do it myself.
