Negative 20 moa mount - Athlon Optics Cantilever Scope Mounts

I got a lemon. Mine is machined backwards so with the mount attached to the rifle the normal way the scope is pointed up away from the barrel. With the mount reversed it is angled the right way. The manufacturer has offered to inspect it at my expense and replace it, which I won't be doing because I didn't want this mount anyway and because why should I pay to fix their problem? Why aren't they shipping me a new mount on their dime? It was just a stop gap while I waited for better mounts to be available. I got what I paid for. Ironically the package says something about quality and machining and doing things right for a good price. I thought it was goofy marketing before I mounted it and I think it's a massive F now. This experience has me seriously reconsidering buying their optics instead of the Leupold or vortex I usually get, because if I get a lemon it looks like I'll have to pay to get it fixed.
