How This company ****med me about R10000

I invested 100 dollars with this company promising 1600 dollars which I earned.I further reinvested 500 dollars by 3 which skyrocketed.Suddenly the trading stopped unannounced and I was asked to pay about 700 dollars which I paid to ensure that my investment continue as per their advice from their admin .After I did that payment It unlocked and my earnings went as high as 95000+ dollars.I then made a request for withdrawal where they asked for my bank details and later sent me an email to confirm that I am due for a payment in excess of R1,377000.Then everything stopped again because now I had to pay R100300,00 exchange rate for that amount. I then said that they can deduct it from my transfer amount which they refused. The person called Sandra,who started recruiting me then put pressure on me to send it even if I borrow from the bank which I refused and started being suspicious. I ended up standing my ground not to pay that amount. This woman insisted that she can organize R50000 for me if I could get that amount. I saw despiration which I couldn't understand then I made a conclusion that it's a ****.Even now after I told them that they ****med me and I blocked them, they used someone else's phone who made a video clip to say it's not a ****. Then I closed shop to say it's over.I however wanted to warn people about a Sandra Dumisane on Instagram, she is the one that recruited me.She would call me but would never answer by her voice which made me suspicious that she may even be a man for that matter.
