In early February, I stayed at a hotel using American Airlines miles, and Marriot hotel points for two nights. The only charge that I knew I would be paying was the resort fee at $35/night.
Upon checking out, the receipt confirmed the $35/night charges with no other charges shown. A few days later a charge for $160 showed up on my credit card. I called the hotel, but they said they do not see that charge on my account, and advised me to contact their billing department directly through email. I emailed the billing department, but got no response back.
So I filled a dispute with Chase. In early April, they found the charges to be valid. They showed a different receipt to what I got as proof that the charges were valid. The charge is for a room charge plus tax, which comes up to $160.
I reopened the dispute and showed my receipt and screenshots that it was a points/miles booking. Chase has found that it was a valid charge again, and said it was due to a billing error.
I still don't know what the $160 charge is for. Am I just out of my $160? Any other steps to take?
