Player can redeem only first promotional bonus chips.
Hello Canj.
Thank you very much for submitting a complaint through our website. Could you please give us more information?
From casino T&Cs:
* Back to back free chip between deposits may limit or void your chance of cashing-out. The Player is entitled to only one free chip in between deposits; any winnings resulting from multiple free chips will be void. For example, if a Player wants to redeem two free chips in a row, players will not be able to withdraw any winnings generated by playing on said chips. The casino reserve the right to make exceptions on the Withdrawals approvals. For further questions please contact Customer Service
I would say that you probably breached this rule, which could be the reason for your bonus issues. Please, let us know if you need further help.
Regards, Matej
