They said they want to review etc, i'm fully compliant and fully kyc verified , don't you think this is very weird?
Not really. Maybe it's just a routine check or something with your account or betting activity set off their alarms. Let them finish their investigation.
If anyone from rollbit wants to help me out asap rather than me missing out on a bet that i want to place right away, that would be great.
If you wanted to bet, why request a withdrawal in the first place? If the withdrawal would have been granted without an investigation, you wouldn't have any money to bet. You would then have to deposit again. Or are you perhaps not withdrawing your full balance and Rollbit has disabled you from betting anything until the investigation is finished?
