You need to provide the casino link because there are two casinos with the same name. It seems one of them is fake, or perhaps both casinos were created by the same person with the intention of scamming:
- spinbetter.games
- spinbetter3n.com/en
In the case of " spinbetter3n.com/en " they had 164 complaints filed against them on CasinoGuro, of which 58 were resolved. You can see more about this here:

Now, regarding the other casino, I'm talking about " spinbetter.games " They have been scam accusations on Trustpilot. You can see that they constantly face scam accusations, see:
https://www.trustpilot.com/review/spinbetter.comWhichever of the two casinos you used, my advice is that next time you want to create an account at a casino, take the time to research the casino. Don't be fooled by the first casino you find and immediately create an account and make large deposits. In this case, you said you had already deposited and withdrawn many times successfully, but now that you want to withdraw $1000 you are having problems. Even so, my advice doesn't change. You may have been lucky with past withdrawals; current scam casinos make selective payments so they can continue scamming for a long time.
For example, this guy:
