That is why many members are skeptical to believe any kinds of accusation to any establishment unless they had shown a solid evidence but at the same time never look down on new accounts because some newly created account have a legit case where they are really got scam by a casino since they have a solid evidence in hand. Aside from online casino players are all around the world and many of them are not a member of this forum.
True, he can just whine or share his disappointment but he should not bad mouth or accused a a platform of being a scam when the platform only did what they believe is the right thing according to the TOS.
Absolutely, I agree with you. I don't want to blame OP in any way, but he expects the casino to respect the contract they made when he placed his bet. So it's also up to him to read the contract in question, which in this case is the terms and conditions of the platform.
If you don't want any unpleasant surprises, you should read the conditions before accepting them. In the worst case scenario, if a problem arises during a slot game or bet that is not covered by the terms and conditions, you are within your rights to make a claim and may be entitled to a refund or free bets as compensation.
Crying scam when a reputable online betting and casino operator complies with the terms and conditions to the letter, seems pointless to me, as no one is forcing anyone to place bets. Furthermore, the problem described by OP is common to many different platforms.
