5dimes has given me "juice free" bets in the past for reporting a bad line. Honestly I think it's fair, if they give Bonus Plays they are going to get every damn bonus whore trying to report bad lines/errors every day.
Do I look for a reward, no..,feel it's owed. Depends I guess on the error, potential cost and my experience with the book. I've been a customer for years and bet daily with you, then a case can be made for customer service.
Some guys in this industry just get it when it comes to customer service...Scotty/Herman at betjm get it, ricard at Phoenix gets it..can't remember the casino mgrs name at bookmaker off the top of my head but he seems to get it. All have been good to me in the past. Can't think of the head cs clerk at legendz but she is good to. Play with the people who treat you right and generally they will reward you in the event you report a bad line.
Tony @ 5dimes on my experience is fair and knows his shit. A bit old school in the way he will put things to you, but I haven't experienced any probs. Fast payouts, reduced juice and solid as they come. Heard issues with their facilities being kinda out dated and the assistant mgmt is a little less helpful but I'll keep playing there to they do me wrong. One last comment on them, if they makes mistake, they will make it right. Was told they would do a free mg payout monthly, I knew this was wrong so o called back..mgmt thanked and honored a free mg even though they didn't need to.
