I think they are doing a lot of hardwork to prove that they are fair 🙂 and they do what they said now they also add server seed thing before changing the seed 🙂it should be enough for them to prove fair 
Does everyone deserve a fourth chance? To extrapolate from one event a user's character would be a very unreliable system of conclusions. However, to get provably fair gambling wrong so many times without consulting anyone (because otherwise, this would have been resolved immediately), I consider that enough fodder to raise some serious concerns about the administration of the casino. bro
