I have not been able to withdraw my capital

I got to know this platform through a family member who had joined and told me about the business, I made my first investment, and I managed to double it in 6 months, from there I started to withdraw my money, but I could only make three withdrawals and now I have not been able to withdraw the bonuses or any of my capital, as I have not been able to do. There are other members of my family and friends in the same condition. I hope you can please help me. Today, June 1, we went to withdraw 15% of the capital because according to them, from June 1 to 5, we could withdraw the capital, and it turns out that they have already lowered it to 5% and that the minimum amount must be 250 dollars.

The following is the original recommendation

No he podido retirar mi capital

Cordial saludos. Esta plataforma la conocí por medio de un familiar que había ingresado y me comento del negocio, yo hice mi primera inversión, y logré duplicar en 6 meses, de ahí empecé a sacar mi dinero, pero solo pude hacer tres retiros y ahora no he podido sacar ni los bonos ni nada de mi capital, al igual que yo. Hay otros miembros de mi familia y amigos en la misma condición. Espero que por favor me puedan ayudar. Hoy 1 de junio, fuimos a retirar el 15% del capital porque según ellos del 1 a 5 de junio se podía hacer el retiro del capital, y resulta que ya lo bajaron al 5% y que el monto mínimo debe ser de 250 dólares.
