I get what you're saying, and I appreciate you taking the time to explain it. I understand that most casinos treat bonus buys as not allowed during active bonuses, and I'm not arguing that the rule doesn't exist.
The reason I'm still pushing is this:
The rule at the time said 'per spin.' Not 'per feature purchase.' Not 'per transaction.' That's what I agreed to. Wildz later changed the wording – and that's what bothers me.
If a rule needs to be changed to cover a situation, it means the original rule didn't clearly cover it. And if it didn't clearly cover it, how was I supposed to know it applied?
I respect your view, and I'm not expecting you to agree with me – just sharing why I see it differently. Thanks again for the input
