PoweUp Casino - Hidden max cashout on bonus

Hello, I logged in on powerup casino after changing my password (they have usually some bonusmoney or freespins left on player accounts to play. I didnt have free money or spins but there was an 150% bonus with thease terms under the big 150% *40x wager* *5€ max bet* and nothing else, they´ve always had all the terms under the bonus *icon* if I could call it that, square box with activate button and all that in there. Well this one didnt have that marked under. I played and then I won 6,465€ from big bass splash 1000 (i have a clip and a screenshot from that) i went straight to chat to ask about my wagering at the moment because it only had % progress shown and i wanted to know the excact ammount of the wager, but later on on the chat I found out that there infact was an max cashout on that deposit but there was nothin telling me that before the deposit, not on their sites terms under terms and conditions tab, I've read them all and have taken screenshots of them aswell. Bonus tab on site with my active bonus still only says 40x wager and 5€ max bet. Chat assistant told me that they have that marked on their public terms and conditions but there was nothing about that, I even took screenshots for them. I fought for a bit on chat with assistant but she/he couldnt help me any further, and asked me to get back to them via email. At this point I am starting to get frustrated and starting to have trust issues over their staff and casino overall, 6,4k€ is big money and im not willing to give up on that. Chat assistant also told me that my bonus will close earlier than it shows on my screen (screenshot on that aswell).
