My BM just cursed me out ... Update: She called and

I apologize as this is long. One of my BM's just cursed me out and hung up on me saying that she didn't have time for my sh*t! Basically this person was pregnant when we ordered the dress and refused to give me any type of guesstimate measurement insisting that I just order something with a 44 inch bust. She lives out of town and has some major marital issues and lives at home with her mom. The dresses come in and we knew it would be big but her mom who she swore up and down was going to alter the dress said she would alter it.When the dress came in her mom said she couldn't alter it b/c of how it 'fell' on my BM. I called and cleared up the confusion and told her if her mom still thought she couldn't alter it that she should give me a call at the end of the week. I even offered to squeeze her into my personal appt with Phyllis that coming weekend but she told me that she couldn't come down from CT b/c she was taking her son to the aquarium. Lo and behold, I am now almost two weeks away from my wedding and my MOH calls today and asks if I have spoken to the BM. I said no and she said I should call her b/c there are dress issues. At this point I am fuming b/c I have bent over backwards in the dress process for her. I paid for her dress and even based my dress choice on what I thought would be the least uncomfortable and most forgiving on her (all of my other bm are twiggies). I call her and ask what's wrong with the dress and she says that her mom won't alter it. I ask what's wrong and she says it's just too big. I ask her if she took it to a seamstress in the area and offered to pay for the alterations and she said she doesn't have time to research a seamstress. At this point, I tell her that I am upset that she waited until a few weeks before the wedding to tell me and then she cuts me off by saying how she has to work and she doesn't have time to hear how upset I am and that she doesn't have to listen to my sh*t and hung up on me. I am in tears and now my already uneven party (another bm had to drop b/c she is preggers and due any minute) is even more uneven.

I have 4 girls (including MOH) and 7 guys (including BM), 2 flower girls and a RB. WHat do I do??Plus I am really embarassed b/c I don't have alot of close friends and my FH has tons and now I feel like a loser who can't even fill out a BP.

Update: She called and left a nasty message saying that she tried the dress on again and it is too big and the more she thinks about it the more she realizes that I should give her her money back! Is she nuts?????
