Honestly, I just experienced this, my friend, precisely yesterday, where I gambled with a budget of around $ 5 and half an hour later I managed to win $ 30, so the total was $ 35 including the amount of capital I brought, I played on a type of slot game at a local online casino in my country and after I waited a few hours, it turned out that all the amount I cashed out ($ 35) had not entered my account, until now I have not received it and clearly that means I chose the wrong casino to bet, OMG honestly it's very annoying.
I have tried several times to contact the service but there was absolutely no response and in the end I had no choice but to make peace with the situation, so it is very important for us to first make sure that the casino we choose is a reputable casino.
