May 1 1, 2065438 bought a platinum diamond ring in Zhou Dajin. I took it to do laundry and cook for less than ten days, and it didn't seem so shiny, so I left it there. I took it out yesterday and wanted to change it. Because I was partial to the ring when I bought it, I called and asked that I had to add 2000 yuan to change it, so I decided not to change it. I went to the store. As a result, the boss disdained to say, I called to change it yesterday and dropped it today. The implication is that I did it on purpose. I said I couldn't accept this attitude and was disappointed with the brand. They only gave maintenance, so will the maintenance guarantee that it will not fall out in the future? The store said that it would cost more than 100 yuan, but the store disagreed. I exchanged it for a lower price. I don't want to make a difference, or I don't agree. The attitude of the store is to either repair or add 1000. Losing confidence in the brand and service made me throw money in. I don't know whose problem it is.
