I have an account there since 5-6 years. Never had any problems withdrawing.
Maybe Steve at sportsbet.io can answer?
Their representative has already responded on this thread(check the quoted posts below), From the response Steve left, it looks like they have concluded the case on their side and are firm on their decision, but if OP is unsatisfied, Steve suggested for OP to contact Sportsbet.io's Licensor and file a complaint against them.
Hi Guys,
this was recently brought to my attention, let me look into it for you..

Hi Guys,
Apologies for the delay.
I spoke to our team (both teams concerned) and they are fine to stick with the existing decision.
Its not an ideal scenario to finish up on, but one I am unable to overturn this case.
So the next course of action would be to lodge a complaint with e-gaming Curacao - which I understand isn't ideal, as it adds more time and energy to the situation.
regards,
Steve.
