I feel bad about what happened to you, but I don't know why you insist that Rollbit scammed you. You are the one who has control over the money that you have deposited in your rollbit account. I have no idea how you play or how emotional you are while you are playing but it seems you are regularly playing having the mindset of taking back all your losses. You disregard all the possible things that might happen after you lose all your money in gambling, that's why the time you don't have any more money + have more debts on your credit card, you are looking for someone to blame for your actions.

At the very beginning, you should have stopped playing and let your losses to where it is. You should have taken a break and not let your emotions take over you and continue to gamble.
