Bitcoin mining trade scam

Good Day

I'm dealing with a scam issue. A lady, by the name of Thuli - that works for Insta Forex - approached me with a "deal I couldn't refuse". She'd told me she was a bitcoin mining trader and she'd promised me a return profit of R20000 had I invested R2000 - I did that through the Luno app. From this point, she was trading for me. Then, the trade wasn't going "according to plan" in which she asked me to provide another R2000 to maintain the trade... Fine - I did that. I then received an email saying that I'm meant to send through R2500 in order to redeem the profits. I was only able to do this a few days later which was a day/couple of hours after I'd exceeded the time required for me to redeem the profits. Because of this, they requested an additional fee of R1500 due to not submitting the R2500 on time. I did this, once again, in the name of this lady, Thuli. The last transaction was done 2 weeks back. Ever since then, I haven't gotten any proper feedback from her and keeps telling me I should put more money in "in order for this whole thing to be processed". I asked her how this process not have reflected by now as it's been 2 weeks already... Mind due, it was not a problem in the beginning but when we're gradually getting to the end of this investment, it now becomes a big problem... This is where I came to discover that I've been scammed from the beginning. Can you
