Jazz Sportsbook group upgraded07.05.2014Sportsbook Review reported in January that the Jazz Sportsbook Group paid over $300,000 in outstanding funds to a handful of large winners that had been on payment plans. These players were regarded as professional users. During the period of time when Jazz Sportsbook and related sister sites including ABC Islands and Looselines were downgraded, no slow-pay complaints were filed from average users. Management claimed this was as 99% of their player base had been unaffected aside from the professional action it had accepted. Since clearing up these larger obligations, no other claims have been submitted. In light of getting their payouts back on the track, the sportsbook family has been upgraded to the mark of B-. Player feedback is welcomed.
