They gave me the wrong wedding cake.
thats really all I have to write. When we went to complain, we were told that we shouldn't have cut it up and eaten the cake if it was wrong (which at a reception is impossible to do)
We refuted the charge with the credit card company and won since not only did they give us the wrong cake, the owner acknowledged it (told us he had 30 other cakes to do that weekend) and offered no help or common courtesy.
