Fairfield Inn Airport review: My 252.75 returned to me.

I stayed at the Fairfield inn out by the airport in salt lake city, Utah. I paid for my room before check in and when I checked in they charged me again. So I paid 252.75 more than I should of paid. Went and told the manager and she refused to refund me the 252.75. I have my bank statement and it's right there 2 charges for the same thing. Its not right doing this to me.
