I bought a green slimming product, and she said that fat-soluble products were not good. She stopped and said it would lead to edema and obesity. Will it?

Please don't buy it. I saw that their activity was 499, 10 kg. I bought it with the mentality of trying first, and it will not work after a few days. She also said that I only bought conditioning, and I haven't entered the stage of fat dissolution yet. She asked me to pay a deposit of 500 yuan, saying that when I started to dissolve fat, my weight would drop by 0.8- 1.2 kg every day, and asked me to pay the remaining 4500 yuan after I prepared the product. I was thinking. I also double-checked with her whether there are any other expenses. She explicitly refused. After about ten days, I ate fat-soluble food, but it still had no effect at all. She also said that I was fat and full, which made me want to order some products. The quotation is 7385, and I originally wanted to reduce 40 Jin. I told her that I could give her the money and ask her to send her a unit price. She also said that all the things she gave me before were finished boxes without unit price. Later, I asked her to help me lose 10 kg. As long as I lost 10 kg, I would directly transfer 7385 to her at one time. This is not too much. After all, she spent more than 5,000 yuan before and couldn't trust them again and again, but she refused. I asked if I could return the remaining products to her because they were useless. She said I couldn't return it.
