Well as of this posting I have been removed from the private FB group, and my log-in for the site no longer works. So now I will tell you the vendor I had issues with it was Mon Cheri Bridals.
They will give me a letter on Monday releasing me from my obligation to them. As for making the gown right they have no intention of doing anything about it.
So as a warning to all brides-to-be do not enter their contest and expect to be treated fairly or professionally.
ETA: Whoa... they completely removed me from the site - aren't they an equitable lot?
