I had a dispute with 5Dimes over parlay wagers I had placed with them. 5Dimes felt the wagers were overly correlated and should be voided out. I felt the bets should stand. We agreed to mediation with SBR. Less than a week later, I was paid in full by 5Dimes.
SBR - Helped me get payed.
5Dimes - Has it's drawbacks, but ultimately pays. That is the most important thing.
