I haven't heard of that name before until now. Looks like it's on coingecko and coinmarketcap.

 How exactly did they scam you or do you just want to know if they scam anyone else?

I notice it has many scam accusations on Bitcointalk if you Google: "Sistemkoin Bitcointalk". I would suggest you Google that up and go through the list of accusation and see if you can find something helpful/useful.
