Bet Jamaica - amazing customer service. They have been upgrading and improving nearly every month since they opened just a few years ago (more props, earlier lines, dime lines, incredibly quick payouts and deposits into the account, Scotty and Shayla are the BEST at CS).
Greek - superior props, some forms of payouts are lightning fast (NetTeller), others (Western Union) are dreadfully slow vs. Bet Jamaica (6-8 hours vs. an hour or less), financially sound with absolutely no concerns about my $$$, slow grading on anything other than the major sports (some things can take hours), average customer service at best.
IMO - If Olympic had Scotty at the customer Service helm, they would be at the top of many lists over Pinny and others.
