Yikes. What do they have to gain from this? they are just wasting yours and their time. No matter the site, when I see something in my "main" balance, that always told me all the requirements are meant (or they're are none), I crossed my t's, dotted my i's and that balance is mine to do as I wish.
Furthermore I just checked their cash games and literally 0 people are playing so it's going to be next to impossible to meet that rollover. If they MUST do it this way, give us a chance to roll it over through the casino or sportsbook.
