this is a very serious situation, I recommend that you alert BTCGOSU about your case and that you are not the only one who has been through this situation, there are more people who are accusing this casino of being a casino scam, you can report your case here:
⭐ BTCGOSU ⭐ THE ULTIMATE BITCOIN CASINO GUIDE ⭐ CRYPTO AFFILIATE OF THE YEAR 🏆
they will not solve your problem, but they can try to contact the casino and with that they can see that the casino is a scam and maybe they will remove that casino from their website to prevent more people from creating an account in that casino scam, you can also show to them this:

these are complaints that other people have exposed about this casino, these are very relevant indications that this casino is a scam, I hope you find another good and reliable casino to play at, it is sad that you have created an account in this casino thinking that they are honest, when in fact they are scammers
