What would help a lot here is if the OP could post any screenshots where his interactions with the BC Game support took place. Keeping that aside, we are talking about a sum of $80,000 therefore the sooner the matter gets resolved the better it will be for both parties.
From what it looks like BC Game should be updating their side of the story on CasinoGuru soon because they have been asked to respond to the allegation. Only then will it be known if there is more to the story than the OP mentioned.
