I ordered and paid for a class ring in a jewelry store. I took them a sample ring and told them I wanted it the same size. They showed me their sample ring and asked if we could have ours like that but with a smaller width. They said yes. We didn't leave our ring because they didn't guarantee it's safety. When we went to pick it up, it was big like the sample ring they showed us. Now they won't re do it without us paying the full amount again and will not give us our money back. What can we do? We don't want to pay extra for a silver ring since they didn't do it how we asked them to.
