Saddest birthday with a torn dress

On the 3rd of March i bought my daughter a dress for her birthday which was on the 5th of March.. The dress that had a factory fault that I only realized when we arrived at the photo shoot.. Then my daughter had a saddest birthday with a torn dress... Then on the 7th went to shop and explained to them they said i must return the dress which i did, but since then haven't received any call from them regarding the issue since they didn't want to exchange it
