Terms and Conditions not fair to the consumer

Be very careful of the bonuses and wagering...After finishing my bonus wagering and receiving a notification that bonus wagering is completed, as well as allocating funds to my account (R750), I then decided to play and won R5500 with that money. When I tried to withdraw it they cancelled my withdrawal and again allocated only a R750.

I tried to resolve however they just point me to the T&C section - stating "3.14) If your last withdrawal has been canceled and the max allowed cash-out amount has been allocated to your PlayLive balance, you would be required to withdraw this value before another withdrawal or a higher value withdrawal will be allowed to take place."

How is that fair to the consumer? If the wager money I won was completed and allocated to my account, with a notification indicating that it is allocated, does that not mean it is now my money to use as I please?

How can I get hold of someone to assist me in getting my funds back from these ********?
