I know it shouldn't have to be this way.. But it is; send her a email asking her where it is at because you haven't received one. She had told me she sent it, but I never got anything. I sent her that email and she said she sent it on Wednesday (it was Friday when I sent this email), and all the sudden, I got a email with my invoice.
Idk If she is busy, or just not THAT organized. I'll be hopeful for the first one.
Anyways, try the email!
