Davids Bridal screwed me!!

My girls all ordered bm dresses Oct 5, 2019. DB told us the dresses would be done by February. Well one of the girls called to pay for dress early on the black Friday sale. DB told her the dresses were discontinued! They never called or emailed me or the bm's. I have 5 months left and my flower girl already has her dress that matched the bm's dresses that are discontinued. I'm just pissed. The Mgr simply said she has so much inventory there's no way she'd know if ANY of their dresses will actually come in. I'm appalled!!!!
