Stuff does happen, yes, but stuff seems to happen far, far too much to trust her to follow through at this point. Stuff's happened for over a year that's quadrupled the production time? And when stuff happens, it's a simple phone call or e-mail to at least negotiate things. She's blowing you off, be it out of fear or just lack of courtesy.

If she's done some work on the thing I'd think partial compensation would work along with sending the items... but again, if she's not talking to you, what can you do?

And if you end up getting nothing at all out of this, as least it'll serve as a big, BIG red flag to everyone out there not to deal with her.

She'll have to decide which she wants: the money for incompete work, or a tarnished reputation.
