Based on the discussion so far, these are my thoughts.
Samo may have talked to you about the service, but since Poison never agreed to Samo's ToS he has nothing to do with this transaction. You got Poison's account banned and owe him 3m. I currently have no evidence or knowledge about your agreements with Samo, but it seems he at least owes you 1.6m. Please post evidence about why he owes you 5M + 1.6M and any agreements you have about that.
