Two great customer service experiences:
DD's 14K ring got totally bent out of shape from her wearing it while playing ball. We bought the ring at Beach Club; I brought it to the stand in DTD on our next trip and asked for repair. They took the ring without question and it arrived at our house about two weeks later, all perfect again. (DD no longer wears it while playing ball.)
DD also has a 10K pearl ring that I bought her from a local shop. The pearl fell out and I replaced it locally for about $30. Once again, about 8-9 months later, the pearl fell out. This time I took the ring with us to WDW. We stopped by the Beach Club pearl stand and I let her pick an oyster. Wow! She got this HUGE pearl. This wonderful woman glued the pearl in place to our old ring and told us that now if it fell out they would repair it for free because they guaranteed their glue! And then she refused to charge us for the pearl!
