OP: I am a little confused. Did you get a folio during the original stay? You mention its your credit card.

If I am reading this right (and I may not be), you had a stay…received all proper paper work….yet the property ultimately did not post the charge to your CC.

The way my expenses work, I would have submitted that stay to our expense system and been reimbursed. My CC is charged and I used the reimbursement to pay the stay. SO, if I were in your shoes, I would have already been reimbursed for a stay I wasn't charged. Clearly owing the property the $$$.

Or do you just submit your CC bill to be paid? Without the hotel charge, you weren't reimbursed.
