I had won at Jackpot.com 4880 eur and they just canceled my winnings and returned my deposit. I did not break any term. This is the email I received from them:
"After an indebt investigation into your account and game play we have established clear evidence that you were abusing our system including irregular playing in order to make winnings.
Consequently, as per section 2.10 of the Bonus Policy:
“2.10 In the event that Jackpot.com deems that a participant has executed any act in bad faith in relation to this offer and\or tried to abuse this offer, such participant shall be excluded from this offer and therefore become ineligible to receive the Deposit Bonus; such ineligibility may be determined and the Deposit Bonus (and any winnings gained from the use of the Deposit Bonus) withheld or revoked, even after the participant's account's award of the Deposit Bonus.”
We have decided to deny and withhold from you any bonuses and winnings and permanently terminate your account, block any access to the account and our services.
Finally, we have paid back today to your Moneybookers account, the total amount of EUR200 that you have deposited into the Jackpot.com account."
