My sister is engaged in cosmetics business in Nanning, but she invests a lot of money. I suspect it's pyramid selling, but she says it's not. I am anxious for guidance.
It's very simple. Just let her go home. Generally, MLM personnel can't leave the den. If she hesitates and doesn't want to go back, it may be. And she didn't answer the phone when she called during the day, and if she texted back later, or someone else answered the phone, it means that 99% is pyramid schemes; I hope I can help you!
