We have them on record stating that a max cashout ONLY applies on free chips, and is stated in the terms. They have NEVER had max cashouts on DEPOSIT bonuses, and so this would have to be a first.
If the terms were not stated anywhere, then what IS stated is that in the absence of any specific restriction, the general terms shall apply.
It is no good saying that this term was ONLY available to players who contacted CS directly, and asked specifically whether there were additional terms that varied from those stated on the website. Most players consider it sufficient to check the terms as published on the website, or within the offer itself, so this was THEIR mistake for thinking up this unusual variation, and then forgetting to publish it. The bonus itself isn't even cashable.
Since Club World is accretited, the course of action is as follows.
1) Send PM to rep outlining the grievance.
2) Wait for reply (a reasonable amount of time, allowing for weekends and holidays).
3) If not satisfied, proceed to PAB.
In the meantime:-
1) Don't post about this any further.
2) Don't make further deposits, or make further play, on the account until the issue has been resolved.
3) Make sure you are not a student
