TRADING APP FRAUD ..KAMAI TRADING

I got some exciting trading offer in kamai trading telegram channel .where in their public page it was mentioned 5k to 25k , 10k to 30 k etc...i invested only 5k to check. they said only 10% COMMISSION they will take which is fine. then they aakes me to pay 11990/ by 5pm today immidiately. I told I can't pay .it was hidden in their plan. i asked for refund for 5k but they said they are not able to do this . so many days there are so many profit earning pics, videos they were floating...live videos ..I think my luck was bad.
