VegasBerry Casino - Changing rules after withdrawal request

I deposited on 11th january 150euros and got deposit bonus. The bonus had usual wagering and I finished it. When I wagered bonus I played 2 slots and I checked on same day what slots are not allowed. Go bananas was not forbidden. I won 3560euros. The casino changed bonus rules after I wagered bonus and after I requested withdraw. Now they removed all winnings for breaking rules because I played go bananas slot.

Go bananas was not forbidden when I played, they added it afterwards. Bing cached page still has page saved and it has NO go bananas forbidden.

Please go to bing cached page and check for yourself.
