I just dropped/removed ONE AU from my Chase Ritz Carlton,

I just want to make sure the PPS card that comes with that AU chase card is properly closed since I heard that once the AU chase card is closed, the sponsorship from Chase to that specific PPS card is terminated immediately, but the PPS card is still active

Any use on that PPS card would be charged based on per visit payment as of $35-ish to the AU chase credit,which would eventually be on the primary account since the AU chase credit has the same card number

I called Chase twice, the CSR can not give me any answer and they say they have no option to close PPS on their end; I called PPS, PPS said only Chase can request to close the PPS card account.

So what should I do???

Thanks
