Sounds like you're being hustled. All card readers are notoriously unreliable, but a reasonable casino (maybe 50% are reasonable) will manually fix database errors that are pointed out to them, call gaming enforcement if the casino won't resolve the issue of stolen comp:

Casinos might treat customers like the soup nazi (NO SOUP FOR YOU ONE YEAR!), but usually they have some respect for a gaming enforcement officer, probably because they are armed and throw around big legal phrases like "we might have to temporarily suspend your license" and "this looks like false arrest". Of course sometimes enforcement is just a whitewash and you have to bring in the big guns, like:
