wedding ring review: cracked diamond in ring 1

My husband purchased my wedding ring from Zales in 2004 he also purchsed the lifetime diamond warranty.The warranty states that the ring/rings are to be inspected every 6 months, in which we bring them to be inspected and the sheet to be signed. I wear my rings all the time and some how one of the diamonds in the middle of the ring has a crack in it, we brought the ring in to be repaired in December about the 6th, Zales told us that it would take about 6 to 8 weeks to repair, one of the sales rep called us on January 29 and said that the ring was ready for pick up, so I went into the store to pick it up, how ever it was supposed to be sized also, the ring was not sized and they said to come back next friday, when I went back to pick it up I noticed that the cracked diamond still existed and something was wrong with one of the other diamonds, I started complaining to the salesman and he told me that zales was not going to replace the diamond, I said that we took out the lifetime warranty and that the diamond should have been replaced. The salesman then told me to call the customer service number and speak to one of the associates, I called and she told me that zales could send the ring back to Texas to be reviewed again and that would take another 4 to 6 weeks, I said that zales should honor their warranty and should have fixed it the first time. I had the ring sent back a second time, now I am waiting to see what type of red tape that zales will try to put me through this time ! I will not purchase any more jewelery from zales and I will call the BBB and send in a complaint about this.
