Man, I was under the impression that half was refundable if deadline wasn't met as well. Oh well

You handled this well imo. She did not, and she should offer some sort of compensation for missing the deadline because if not, wtf. You are breaking the initial agreement if not, con dates or whatever are not a vague suggestion, people want it by then for a reason. I just fhgdgf, the concept is not difficult

Best of luck :I
