That is no accusation. The person who made that post didn't even include any specifics or proof. He just says that the withdrawal was not processed and that all. A few weeks back he made a post in this very thread claiming that winna.com is a scam but again without posting anything else showing that he was scammed
I am starting to think he is just a troll.
There are always persons trolling each casino that looks to be doing well. It is only those who are unaware of the antics that will easily choose to accept scam accusations against casinos without proof.
In the legal environment, you hear "onus probandi," which means "he who alleges must prove."
It is not proper to just accuse a casino without good proof; what is worse is to accept a bad name labelled on a casino without evidence.
