Hopefully waiting to see the solutions of all above problem. If cant solve the problem then there will have no option except creating scam accusation.
How long have they been down for without any sort of official notice or anything to say don't worry funds are safe? usually that's one of the first things some one would do if they were doing any sort of exit scam to get people who are panicking to relax long enough to get every ones funds out and safely get to some island some were safe from the law.
