So, I got an AU amex Platinum card and then got the PP. I didn't realize i get charged for PP lounge visits. After my trip I canceled my amex and didn't care that the PP would be canceled too. I get a letter from PP saying they tried to charge the amex card, but they cant because I don't have it anymore, and that I should provide them with a new card to charge. Could that hurt my credit score if I don't pay?
