It is confusing to have different information. The terms is clearly say that to withdraw money, players need to wager at least 50% of the deposited funds and OP said about 300%? One other thing about the 5% bonus, OP said that there is no additional wagering requirement but you say 40x? Yes they should clarify about this to avoid confusion or better if they can have separate page to tell players the full information of the bonus.
Clause 8.9 of the rules states that a player may be refused payment if the user does not place bets in the amount of at least 50% of the amount of money deposited to the gaming wallet, with a coefficient of at least 1.5, so you need to fulfill these two conditions.
