Amazon mall

I joince their platform via facebook, as they advertise part time jobs. I registered my mobil number then it connected me to the manager on whatsapp. She explained to me how their platform works. I agreed to join, he sent me a link to register of which i did. I was told to download a telegram and sent a link to add the amazon mall and my tutor. After registering to the amazon mall, an account was made for me. For registering i was topped up with R51.00 then i was told to deposit R100, my balance was R151.00. I started taking task of which the second task require me to deposit money in the account, i deposited R80.00 and i complete the task. My balance was R440.00, i made a withdrawal of R200 of which it was deposited in my account. The tutor sent me a massege asking for how much task she can book for me. I told her for R300.00 and i completed the task. I had R650.00 in the amazon mall account. I complete few tasks of which i earned commision up to R1800 then that is where the prolem started. I was given tasked to complete which keep on increasing to high amounts. I deposited R1550 to the account then completed the task after that, i had R6600.00 in the amazon account. I tried withdrawing it it refused. I complained to the tutor and i was told that i have the last task to complete that is why i could not withdraw. Only to realise that the task is a high amount of R10 772.00 and they said as i have R6600 in the account i need to deposit R4165 to complete the task then will be able to withdraw. I did of which it didn't happen, it requested R10441.00 i told the tutor that i dont have it. I'm no longer interested i want my money that i deposited, i was told to make the deosit or i will loss thee money i deposited. Your help will be highly appreciated.
