For relative ease of resolution I hope that the hotel is still PC affiliated. I have seen the following kind of thing happen: the hotel left a brand whose loyalty program points were used to pay for a hotel stay but then the hotel double dips at new and higher point costs just weeks before the hotel formally exited its loyalty program affiliation. Some Scandic hotels did this with Hilton HHonors and Hilton HHonors was completely useless in trying to fix the mess, while Scandic would point the finger at Hilton.
