free chip bonus says max cashout $100 but cashier capped me at $50

Used a free chip promo that had the terms clearly saying $100 max cashout, did all my wagering and made it to $118, but when I tried to cashout the cashier only let me request $50. I double checked the T&C and it still says $100 max for this one, so I’m a little confused if I missed something or if this is just something that happens sometimes with these promos. I didn’t see anything in the fine print about specific caps for the cashier or separate withdrawal rules after you hit the max.

Normally I’ll just chalk this up as bad luck but this kind of stuff is why I’m skeptical about playing these “no deposit” slots offers too often. Has anyone else run into the cashier limiting the cashout below the stated max for a bonus like this? Not sure if it’s worth arguing with support, or if they just always go with whatever their internal limit is. Just seems odd when their promo page was clear as day about the $100 cap.
