On 10/27/2012 12:12:10 AM you've redeemed a Free Chip for $50 with code NDB50
On 10/27/2012 3:07:51 PM you've redeemed a second Free Chip for $50 with code TRYPARTY50
No deposits are detected in between free chips. As per casino rules:
"Unless the Casino management specifically gives prior agreement, welcome bonuses are limited to one promotion per Player, per family, per computer, per address.
The Player may not consecutively redeem multiple no-deposit bonuses. Free chip offers are meant only for our regular loyal players and unless otherwise stated in order to cash out on a free chip offer you should have an active depositing account. Should a Player redeem one no-deposit bonus and then be subsequently offered another one, the Player must make a real money deposit into their account in the interim in order for the Player to be eligible to redeem the second no-deposit bonus.
In the event that a Player redeems a no-deposit promotional offer that he/she is not entitled to, any winnings generated from that promotion will be voided."
Casino voided winnings generated on second free chip since you've redeemed a second free chip with no deposits in between each free chip as established on Casino rules
Hope this clarifies the misunderstanding
