Switched to VBet Cassino here https://vbetcassino.br.com/ after the same frustration and it's night and day difference. Withdrew R$2,800 from blackjack last Friday night - money hit my account before I finished my drink. Their live dealer tables are actually enjoyable too, with professional croupiers who remember regulars. What really shocked me? Their support team fixed a bonus issue I had at 3 AM in under 10 minutes. After 5 sketchy casinos, this one restored my faith.

You need to understand that bets are often not only winnings, but most often they are still losses. And you need to understand that if you really want to win on such sites and in such games, then you can’t do without your own strategy. And to calculate such a strategy, you need to play on the site at least. And it’s best to play for small amounts to save your money until the right moment. 
Of those sites where I was recently lucky, this is in particular a site like Сhicken road and my winnings here were quite good.
