Sorry, don't mean to sound harsh, but that just seems so weird to think that anybody would make that mistake in this day and age. This lesson has been learned and shared and reshared and written about and blogged about and discussed to death.
Nonetheless, you guys did a lot of hard work and it sucks to have things not go well. Sorry to hear, and I hope things improve down the road.
Edit: Sorry of this came off as overly harsh. I'm not trying to be mean-spirited here. I'm just a little surprised by the details of the story, given the context. And I don't mean to suggest that I'm better than anybody or know better, etc. I'm just some nobody who haven't proven anything yet, so feel free to ignore me.
