<prompt> Human: I made an online reservation with a hotel, and never received confirmation, so I called to see if they had it. The hotel said they didnt, so I made a reservation over the phone. I checked in to the hotel, and again they only had one reservation. Later that night at 7:30pm, they called and said they found the first reservation, and I was responsible for paying for those rooms as well. I said I was not going to pay for rooms that we had confirmed that I didnt make a reservation for, and if they charged me, I would file a claim with my credit card ChaseVisa. They did charge me, and I filed a claim. Now the hotel is calling me. My guess is that I should ignore their calls? Could this get sent to collections and hurt my credit score? Any help is appreciated.  <response>: Id answer and see what they want. They may offer to refund you the unused stay if you withdraw the chargeback.
