To clarify, it's not related to anything in our sphere. It's an alleged, very serious matter and once we receive requests like this, we must allow them to complete their investigation uninterrupted.
The investigation has nothing to do with the activity on their account, but the source of funds.
Just to make this clear, who exactly is asking for this investigation if not rollbit?? The odds provider or any slots provider has nothing to do with funds, they just offer the games. For them the money is just a number, rollbit is controlling and managing the deposited funds, nobody else.
Rollbit is blaming this on a third party. As you said, it’s between Rollbit and the OP. Rollbit decides if they are going to pay.
The OP has been playing for 2.5 years. His bets aren’t that large to raise a red flag. He wins $33k in the casino and all of a sudden there is a serious claim on source of funds. The wagers are too small for concerns on source of funds.
