When this player registered, was there any max .12 btc rule?
You can't change the rules mid-promotion and enforce them on players who have already signed up and played.
It's your job to establish the rules before the promotion. Players will always take full advantage of any promo you offer by the way.
You are absolutely right here, the max available sum to cashout was missed and added later, we don't deny our fault here. Now it's stated in all new promos from the very beginning and also described in T&CHey,
quit ignoring me, that's rude.
You agree with me admit it's your fault, why won't you make it right?
