Nice one mate, filling a law suit against a casino would make them seat up in discharging their duties as they signed up for. If the ole777 casino do have an office over there then the law  suit against them would make a good sense as they would be taken up on their charges but if o may ask, have you engaged in such exercise before? How do you generate funds to pursue up with the legal fees attached to the law suit for which you want to embark upon? I hope you would not get members here to paying for the fees just as a poster had said here because that would or might result or amount to other members likely seeing your act as a means of scamming members in the name of legal matters.
So I would advise you create a thread listing categorically how you intend in follow up with the case till the end so that those interested might join you in the course.
