The advice is actually right, you need some serious help their buddy. Asking for a refund after losing is never going to happen if it's an outright activity that you did there.
There's really a serious matter on your case OP and those are signs and you have to admit it and don't put the blame to any casino where you voluntarily deposit your money and gambled with it.
Yes, you are right. Before we gamble, actually, we know that gambling can make us lose our money but we deny that and still deposit the money and play the games. Some people make money from gambling while other is not. Blaming the casino because of our loss is not good behavior because we know the risk and the casino is not asking you to deposit more money, but they only give you the promotions that you can take or leave. The choice is up to you but most people will take that and not try to blame anyone because they know the risk.
Yes, we already have understood that gambling can either make us win or lose a lot of money. Taking action and then losing while looking for the casino to be blamed is showing what the attitude of the gambler is.
Hopefully, those who lose a lot of money will not complain to the site because they realize that is the risk that they will get if they use too much money. Sometimes I just smile if somebody blames the casino just because they can not get their win money or feel scammed by the casino but the real mistake comes from themselves.
The basic rules that will always stand in the casino are when you deposit to play and lose and there was no cheating involved, you cannot ask for a refund, because if any casino grants that request it will be exploited and abused, and that will be a big loophole in a casino operation especially if the casino has huge members and the casino do not have the manpower to address this exclusion request in a timely manner because of the so many tickets.
That is the thing that we should know but the problem is most people are not ready with the losses and still blame the casino and ask why they did that. The casino is nothing to do with what you did because you have your awareness when you deposit the money and play many games and lose that money.
