Well, anyway, I managed to place another €52 worth of bets, and I’ll be happy if I get a €120 payout from a €3 free bonus. I’ve emailed them about everything under the sun, but they don’t understand a thing—they’re absolutely ridiculous! There were probably a few cents left in my account from a previous deposit, and the system picked that up—I don’t know, that’s just my guess!
It's an error in their system and live chat is clueless as usual. Formerly, these same or similar issues have for other players been resolved by filing a complaint through one of the services doing that, like AG.
When I play through a whole bonus and want to withdraw immediately after, the system says I haven't wagered my deposit 3x even if I have wagered it like 20x and that's another flaw in their system.
