Scoin Scam - S coin scam

I got a message from a number telling that to earn money , I also didnt trusted. I thought I can quit when they ask more money . Initially it started well but later they given some tasks , while starting they told you have to pay only *K+*K. I tried and opened it after paying first *K they asked to pay *K more , i questioned but they told , no worries pay this time , you will get total money back like that. I thought my *K will not come , so i invested more *K , then again they asked **K. So i told I need to quit , now they are not giving the money I invested also.
