Sounds like a custom kitbash.
Ah. Google is my friend, I see what I suspect you bought.
That looks like a badly cast illegal reproduction of an old Fan-made mini, the Dark Angel. Suspect you got it from someone in Washington State, where a very well-known repro caster lives? A real Dark Angel looks like this:

The genuine Dark Angel was made by folks on the Lords of the Battlefield forum, and a limited number produced. I have one. Crisp, clean details. If what you bought is the thing above, unfortunately you've been ripped off - it's apparent that there are lots of casting issues, even after a heavy coat of white paint.
Pro tips - don't buy from Washington State. Don't buy minis which show up slathered in a heavy coat of paint, which is designed to obscure problems caused by cheap & nasty recasting.
Lots of advice can be obtained from the members here. Sorry for your bad luck.
