Whatsapp Stokvel ******** using Capitec

Please please please urgently help!! There is a WhatsApp stokvel group which is a **** and is using capitec clients to **** their money. They promise people that if they play with R200 they get R1000 back. I want my money back as I have found out that they are ********. It's a group of people who create the group and once they have the money they secretly create another group. And once they see you have found out they remove u even though you have not got your interest back. I have proof of everything and the fellow individuals I sent money too. Please I need my money back.
