What transpired the case? What really happened for them to took your money. Your explanation is not clear for us to understand and put blame on them. As it we don't know who to blame, whether you or mixertumber.org or com. And also you do not bring evidence of Scammed asset. You would have brought an image to clear the forum that what you are saying is the TRUTH. Now how and what do you want us to do? It is to avoid them. But there is no concrete evidence to nail them on the wall.

Okay let us assumed that they scam you and later days they returned your money back to you. How it happened? Tell us more about the transaction. If you provide proof, it will be more easier to avoid them.
