I would just dropp the stuff off on the steps and drive away. If you leave it at your place she can claim A) B) &C) blah b;ah....so go to her place leave the things there. Then send her a message (I'd call...99% sure she wont pick up when she sees it's you) and say I've left your things like you asked. A recipt will be on its way to you and leave it at that.
