Probably you might show a suspicious activity on your betting history that trigger the casino security.
Do you try to click chat with agent when you open the live support feature? Their live support typically few minutes to hour once you send an inquiry.
Maybe you will need KYC.
When a casino pulls a trigger card like this, it is often based on mulitple suspicious actitivities and they will even investigate that account further. The user can contact their support team for further appeal and guide to prove that he did not break any ToS of the casino.
Case like this might take quite a long time of investigation from the team as well as their final answer to the user's appeal. If it was not trigger falsely, chance to appeal successfully is very small. Because if it is a positive trigger, the user will have nearly no chance to prove his innocence.
Betbolt team is active in this forum so they will see this complain and give their support to the user very soon.
