I had my wedding dress cleaned but there is still a stain?

Shortly after my wedding two years ago I brought my dress to a bridal shop and had it cleaned and preserved. They put it in a special box and I have been storing it in my closet ever since. I recently decided to sell it and when I opened it up today the first thing I saw was a yellow spot on the bodice (not there when I gave it to them) and deodorant marks in the armpit area on one side. Additionally, there were still some grass stains under the train and dried grass floating around the box. Does this sound right?my wedding dresses I understand not all stains come out but shouldn't they have told me if the deodorant stains were unable to be removed? And isn't preserving it supposed to prevent the yellow marks? Should I bring it back to the store and complain? I don't feel I can sell it in this condition and I'm really upset.
