Did the casino support actually say that he doesn't understand what you mean? or he said that doesn't know why the sportsbook section redirects gamblers to another website.
I was having a bad experience with lazy customer support where they straight forward answer my question by just posting their TOS link.
exactly this! and it is very annoying. I've had my fair share of casino support that just posts links to their ToS despite asking for something that has nothing to do with their ToS.
