I voted for Leo based on my experiences before the market change, but just finished my re-registration on the Dutch site the other day..and zero issues: in fact very pleased!
Sorry to hear you had a rough start but im sure if you give it time they'll fix w/e went wrong for you. At least they always used to be on top of those things. I can imagine they have limited support in the weekends, especially in fresh markets were it may still be a bit of a beta run, so to speak
I mean, my chat session was short, friendly and helpful, and that's how i like 'm, and the welcome bonus was also to my taste. I like their wager x amount of raw cash to get the matched amount added instantly as cash afterwards. Really good if you play often, and these are then +EV since you're never tied in to any silly bonusrules.
The only thing i noticed is that some of my fav games are missing on the .nl site, and the layout is somewhat different than i was used to, but it's fine. I won on my first depo yesterday (got the 100 extra cash and the free spins unlocked after wagering 2K), than took up the weekend bonus in my account today. From the looks of it there are promo's throughout the week, so it all seems to be as i remember basically.
Cashout was pretty much instant and hassle free (literally no doc's after sign up process, and within 3 seconds confirmation mail was in
So yeah, i assume it will pick up for you once you get a hold of them
