Wintomato is actually a casino I personally do not trust, though I can't categorically refer to them as a scam, I do not trust them due to some previous cases where some user here had some scam allegations against them, though the issues were said to have been resolved, my spirit will not just see the casino as one I am willing to use or play on.
Unless you have other notable issues with win casino. You cannot say because there was an allegation against a particular casino, so your spirit no longer accept them. This is demarketing. I do not think that there is any single casino in BTT without any kind of accusations at any point in time. All of them has been accused at one point or the other. But what differentiates a good casino and a scam or the one intending to scam is their ability to resolve the accusations. Meanwhile, some accusers accuse falsely.
And coming back to referrals and commission, I would suggest you read their terms and conditions regarding that area and see what they said about that, there is no way they wont have some rules and guidelines written down in their terms and conditions concerning affiliate marketing and commissions, or better still, contact their customer care to help look into your care and see what exactly is wrong and why you are not getting your deserved commission.
This is what and all I can suggest for now.
This is a good suggestions. Many gamblers and including myself see it as a waste of time to read terms of services of these casinos. And ever since the casinos understood it, they have been using it against us.
