My 90,000 TL Devex Investment is Gone, and I Can't Get It Back

I put 90,000 TL into Devex investment company after being introduced to it by a person named Ö***  who I met on Instagram and who claimed to be an investor. I'm afraid I have to say that most of my money has gone down the drain. I told them that my daughter is a diabetic and requires insulin. I also mentioned that I am in urgent need of the money. I've been trying to get my money back, but they still haven't returned it. I even asked my bank for help, but they said the company's request for approval was necessary. I want my investment back from Devex Investment Company. If I don't receive it, I will share my complaint publicly.
