Well, you have to observe closely to make sure you are following the referral program rules and what Win Tomato's stances are concerning their referral commission, many of the casino's referral commissions have a lot to do with what the team's final decision is on how much to pay as referral pay at some point.
So for that, I believe what you get as a final referral commission depends on the decision of the casino team, so they decide what amount you get at the end of each month,, that is what most of the casinos do when it comes to referral payments.
On many casinos I know like example if I will get like example 0.1% from total wagered from referrals,or like example 50% amount which referrral losted.Also there is no on FAQ or T&C any explanation about their account level up referral points rules they didnt even writed anything about it and when I ask about that on WinTomato telegram group moderator even dont want to answer to that,I asked maybe 10 times moderator ignored me many times,moderator just writed me read your account profile or read FAQ but there isnt answer to my question LOL.
