I am a player who can make deposits of 200k usd in one day. I played for 9 months, almost every day. after a series of winnings, I was accused of having some accounts associated with me. They take 185 thousand dollars from me. This is Metaspins Casino. and they claim that this is normal. they just make sure the game is safe, so they are forced to steal 185 thousand from a “VIP” player.
If you are a player who can deposit of 200k USD then I assume you are a player who made gambling a way of living. Casinos do not like your type of players. They like players who are occasional, go to them for fun and lose and leave.
On the other hand when a gambler become professional then he use every possible opportunities to gather information to manipulate odds or to take advantage of the house. They can continue it for shorter terms but for longer terms eventually they get caught.
In your case you accused metaspin, metaspin responded but I do not think there are anyway to verify that they are telling in response. If you think the screenshot is enough for you to go to the court then you can have a lawyer and escalate it with legal aids.
