online casino paid cashback to bonus balance instead of real balance

Just got hit with something weird on my last session. I lost a chunk playing blackjack and saw I had some “cashback” coming, which should’ve taken the sting off. But when it hit my account, it didn’t go into my real balance - it ended up in my bonus balance, full of rollover requirements. That kinda defeats the point, right? Cashback’s supposed to soften the blow of a loss, not tie your funds up in more restrictions.

I checked the promo terms again, and maybe I missed something, but it was not exactly clear about which balance the cashback would go into. Wondering if anyone else here has had casinos do that or if it’s just a gray area trick some are pulling now. How do you guys handle it when your cashback comes as a bonus instead of actual cash?
