Even if there’s no proof with regards to this one, still Roobet have to answer this but since OP is not active and I can’t see Roobet representative here it left us guessing for what happened on this account. Maybe there’s an error or what that’a why the bet is voided but still its better to answer this. Maybe we can expect a lot of this if this left unanswered.~
The proof he brings here is not complete enough and Roobet customer service already answered his issue. There is really nothing concerning, actually.
