Issue with dress on wedding day - boutique offer

My wedding was in September and I reached out to my boutique I purchased my dress from because the boning that they added into my dress ended up popping outwards and into my skin. I was super uncomfortable during my wedding day because of it and it ended up cutting my sides. During my alteration appointments I pointed out that one side stuck out and they assured me not to worry and when I went to my next appointment it wasn’t popping out. So I didn’t think there would be anything to worry about until my wedding day. I noticed much later in that the side was in fact popping out! You couldn’t tell from the dress hanging so I didn’t think anything of it when we were getting ready for pictures. By the end of the night I was begging to be unbuttoned out of my dress due to pain. I reached out to the boutique and they said that they can have me go in to have the dress fixed or refund me for the boning portion. I looked it up and it seems like that may be $60-$100. I don’t mean to sound ungrateful but I paid $800 in alterations and they told me to add boning in to create more of an hour glass/support. I was fine without it but trusted them since they’re the professionals. Now when I see my pictures I’m so upset seeing the side pop out. What should I do? Just take the refund they’re offering and move on?
