I know for a fact on William Hill & William Hill Casino Club, you are prompted with a pop up window asking you to accept the bonus and agree to the terms and casino of the bonus (with a link to the terms of the bonus itself) and within these terms it will tell you that a wagering requirement of deposit (10) plus bonus (2.50 = 12.50) x 20 will be applied to your bonus. As such, your the one at fault for a) agreeing to the bonus and b) not reading the terms of the bonus before you accepted it. Casino's can do little more than prompt you to accept the terms and conditions of the bonus, if you choose to ignore them, you cant really bitch and whine about it when you done abide by the terms which you accepted. Your best bet is to speak to Hills explain the situation and if there in a nice mood, they might reduce the wagering requirement for you or sort you out in some way however jumping on their LiveChat calling them a bunch of robbing bastards, is not going to get you anywhere.

and trust me i know better then anyone on this subject
