As long we dont see any proof or feedbacks about that then its really hard to believe on with this situation.
Even if proof or feedback is provided in the future, it won't change the fact that this is a scam sportsbook and it isn't safe to invest small or big amounts here in my opinion.
How many of you or i mean how many account will be created like you to Shill for this Scammers?
and do you think people here are fool enough to believe your Vouching ?
There is a possibility that this is a legitimate account who actually got their funds back, but this single case won't be enough to reverse their reputation which will most probably stay negative in the future.
