Kaak Economic — Fraud E-Commerce

I paid 2000rs as a joining fees. They assured to return 3200rs with monthly usage limit of 800rs each for 4months.
It's been 2 month since I joined nothing I received back yet. They have a third class app from which one cannot buy anything. Always their servers are down. I don't know whether the owners know about chain marketing or not. Always he shows big picture but nothing works out. Request all not to connect with this worst team ever.
