Wow. They really cut off your freeplay because of what you wrote on this site? That's pretty weak.
Do you know specifically what you wrote that angered them? Was it something from the main Alanbestbuys site, or this forum?
Also, while I am not defending them, I don't think they "cheated" you with the bounceback. As far as I know, bounceback offers are not guaranteed. You may feel you "earned it", but in reality, bounceback isn't actually a rebate, but rather a way to entice you to come back. That's why they don't rebate you on the spot when you lose.
I understand your point that you can say you only played with the belief that you will get offered bounceback money if you lose, but since that's just a promotion, they have a right not to give it to you if you piss them off.
I think the real story here is the fact that the Rincon punished you for expressing your opinion about them.
On a side note, I haven't been to Rincon since February, and for whatever reason, my September offers increased over anything I've had in 2015. I'm getting $120 freeplay per period, which means I can get $240 if I stay overnight between periods. Still, it's not worth driving all this distance for just $240 of freeplay. I might see if I can do a visit just to combine it with a San Diego outing, though. Too bad September isn't really a good month for me, as I just don't have much time to take trips this month.
