On May 13, the diamonds bought in Lao Fengxiang did not bring much. Put the box and wait for October 1 to get married and take it out. It is found that turning black is just like rust.

When I bought it, the clerk said that it would be a bit bigger to take the master. After changing, I did n’t bring it. Now I find that the connection between the two sides is black and rusty. Can I return the goods? How to complain if you do not retreat?
