Kinda looks like that, after noticing u came back and gambled some of your winnings while waiting for a WD, the stalling tactic of pretending your documents are insufficient in hope you gamble it again didn't work out for them. So they felt they had no choice this time but to just take your money and point to some seriously bent terms.
Just reading the general terms on this shady as shit site they refer too:
"F. (Cut out a huge chunk of horseshit written here) Irregular Playing Patterns shall include, but are not limited to the following activities:equal, zero or low margin bets or hedge betting,placing single or multiple bets of a value of fifty percent or more of a Bonus on any single game, individual hand, single Bet or round;building a balance and significantly changing play patterns; for example, Bet or wager size, Game types and Bet or wager structures etc. in order to meet the wagering Requirement;placing large Bets or wagers which result in a substantial gain followed by a drop in Bet or wager size equal to or higher than 65% of the previous average Bet or wager size;reserving real money funds in any incomplete game round in order to use bonus funds before real money gameplay is completed;making large Bets or wagers and then substantially reducing the Bets or wagers to meet the wagering Requirement;moving from a low weighted Game to a high weighted Game after a large win for the purpose of meeting the Requirement;on roulette, in the following cases: (a) covering 24 or more of the 37 available numbers; (b) betting on red and black; (c) betting on odds and evens; (d) betting on 1 – 18 or 19 – 36 (inclusive); (e) betting on all three columns of the table layout; (f) betting on all three dozens;on baccarat. (Cut out much more horseshit here too)"
So, if you didn't use a bonus, I don't see now an honest person could attempt to enforce the terms they snipped and quoted to you. F is also named Illegal terms on their site, not prohibited. the term they claim you breached (betting more than 27 numbers on roulette) that they also quoted you, looks, to me, like it has been snipped from the general terms once again. But again not reading the same, leaving out the full sentence which seems to state "for the purpose of meeting wagering requirements" . How convenient.
Fkn jokers. Sadly, this industry is full of 'em.
