Review of Le Meridien Bora Bora

So I booked 1 night on Marriott Points and was told I'd be charged $4 total. After doing that I booked another night pre-paid. Well the hotel charged me the full rate for the points night and REFUSED to return my money. They didn't indicate this at any time and just stole my money. 2 Hours so far on the phone with Marriott and they refuse to abide by Marriott's policy of not charging a full price and taking points. No way are they getting a 6 month $550 loan from me in hopes they will be honest and actually refund my money. In my 30 years of international travel, this is BY FAR the worst experience I have ever had. I would not expect service this poor at a Motel 6.
