Is the jade in Kaiyuan Jade Workshop, No.99 An Xiang Yan Road, true or false?

I don't know if it's true or not. I bought a piece of hibiscus jade on March 29, and later found that two pieces were missing from the bracelet. I thought about it, but it cracked after wearing it for two days. I went to the store to explain the situation, and the salesman said there was no special price after sale. Why not make up the original price of 3,000 yuan? I bought it in 600 yuan. At first, I said I could make an offer, but something went wrong and it happened again. I said it was a quality problem. I haven't left a stubble here. I cracked it myself. As a result, the other party said that you took it back artificially and it was broken. We are not responsible. Then, several salesmen who kept telling me that we were irresponsible dispersed in a hubbub and left me hanging there, hehe! Today, I went to the guide who took me to Kaiyuan Store for help. I promised to help negotiate on the phone before. As a result, I went today and was refused to negotiate on the grounds of "admitting that it was man-made damage". I didn't even see the manager, so I made a trip for nothing. In short, if you don't understand jade, you should buy it carefully to avoid repeating the same mistakes!
