casino counted my blackjack wagering at 10% even tho promo page said live games count

Was chasing a bonus this week and made sure to double-check the promo page before playing, since getting burned before by those sneaky terms. They listed live casino games as eligible, no fine print about blackjack having reduced weight. Ran a bunch of hands at the live tables, expecting 100% toward the wager, only to find out after I was only credited for 10%. Customer support gave me the usual copy-paste about "contribution rates" and said it’s standard, but nowhere in the promo or the FAQ did it warn me.

Honestly I try to keep expectations measured, but if they’re gonna pull this stuff, it makes trusting the promo info feel like trying to play roulette with two zeros and a missing ball. Would be different if I missed some rule buried in the promo text, but I checked twice. Anyone else get their action counted wrong like this? Curious what you all have seen - feels like it’s getting more common and I’m just trying to tape my sleeves down before jumping in again.
