Definitely not because They are pretty much just providing a bad support service and that is all. This is a quite big site and there will be always people that wager there , so what they done is pretty much just leave the site and hope people will lose there without caring on their players . They do check on issues but not regularly ( after complaints )

totally shows that the site still has some activities although the wagered amount seems to be lower, could be that they are either having a bad week or that some people are leaving because of their horrible support service and some not creditted deposit issue
