Crypto Scam Report

Long story short. A few of us here in South Africa invested in crypto hallmark. When we requested a withdrawal, all the hidden costs suddenly popped up. A 30% fee was charged and we asked numerous times that if the up line pays this 30% will all the down lines be able to withdraw. YES was the answer more than once. Then another 10% was charged, asked again, will all withdrawals be released. YES again. Our investments have not been released. Now apparently all investors have to pay the 30% and the 10% None of this information was mentioned when we invested. We are being accused of running multiple accounts. My friend ran mine and his mothers accounts as we are new in this. What does it matter from which platform i log in from to check my investment, it is after all my cash and my investment and i use my personal passwords. Every investment was made from our personal bank accounts with our personal emails and all relevant documents were uploaded and we invested through either luno or old coin trader and then in to crypto hallmark. Now they are coming up with different amounts that have to be paid in order to release our withdrawal requests and holding on to our investments. When we queried with Amos Miller, he just said my apologies. Thats it!!! How is this legal??? How do we get our investments back? This Amos Miller clearly lied and is now holding on to our investments.This is hard earned money which we thought would help us all through these difficult pandemic times. We have telegram conversations as proof as well as transfers being done in to the platform. No upfront information was provided, Amos Miller also said during our conversations that unfortunately the extra charges only gets made public once a withdrawal is requested!!! This is blatant lying and hiding the truth!
