Many crypto casinos that have a good reputation in this forum, why play on a less well-known platform?
And Im sure those 2 platforms never post or promote their casinos in this forum, sorry to say but it seems they will not respond to your complaint here.
How about bring the dispute to casinoguru, because if I look at Wazamba rating on casinoguru it is considered a good casino.
For sure there are many reasons why OP still wants to play on those online casinos, even though as you said that they aren't well-known platforms. Based on my own experience, one of the reason why I still play on casinos that aren't even trusted is because of the promotions they offered like free spin without any deposits requirements. But even so, it is of course best to avoid these kinds of sites as much as possible for also to avoid this kind of problem, even if they offer good promo.
What reason? For promotions? or other thing that he think beneficial for him? Since if he just look at those things then for sure there are lots of casino here can offer such promotion he's seeking and there's no point for continue if he knows that the casino he's playing is a compromise one since that's already an indicator for him to leave that casino since anytime he would really experience those unwanted scenarios happen to other people.
This indicate that we should never get attracted on the offers since those scams or bad casino is just using that so people will get interested to try their casino. After they wager huge amount of money then they might start to experience some thing that they don't like to happen. So that's a lesson that need to learn from and we should stick on the casino which already gained a good reputation for long years since we have a lot of them available in bitcointalk.
