If you always use a VPN, then you should be paid in full. There is no proof you played from a banned country.
True, but I'd add you should never withhold winnings from a KYCed customer period after allowing them to play + win. Especially after they've waited for their withdrawal for days with minimal comms.
It seems very rash to close my account mid-chat and try and erase my pending withdrawal, but may just be how this Rollbit choose to operate - money first and player second.
