yeah usually a trick like that is performed at a shadier-looking establishments (or even on the streets), if you haven't seen something like that before it's easy to fall for it especially if alcohol is involved
basically you had no shot, the thing would've keep rolling 28 or whatever the **** it needs to land on to double your bet so eventually you'd be forced to quit even if you had $100M cash on you
pretty sick that they resorted to pretty much straight up robbery I wonder if there are any kind of regulating bodies there that can do anything about it
update: found an old link for you OP apparently they've been pulling this kind of **** at various resorts for years

Gambling: Many Americans have reported losing large amounts of money at Dominican casinos by playing a game (or variations thereof) known as “Super Keno,” “Caribbean Keno,” “Progressive Keno,” or “Progressive Roulette.” Players have complained that the game’s rules are unclear and/or misleading. Casinos have also been associated with cases involving credit card fraud.
Any complaints arising from a casino should be directed to the Office of Casinos at the Secretary of Finance. To register a complaint with this office, call 809-687-5131, ext. 2120
if I were you I'd start by calling your CC fraud dept first and dispute the charges. GL
