What strikes me as odd is that she spelled your name four different ways. I mean, anyone can make a mistake and misspell a name, even if it was carefully spelled out as you obviously did. So if she'd misspelled it the same way every time, it would just be a matter of the correct spelling not sinking in.
But spelling it four different ways smacks either of incredible incompetence or deliberate obnoxious behavior.
Yeah, I'd talk to her supervisor.
