I know Chase will refund an AF if you cancel the card within a certain amount of time (I've varying reports between 60-180 days). Will they refund (or at least prorate) the AF if you downgrade? If you downgrade a CSR to an CSP 59 days (assuming the limit is 60 days) will they give you a refund of the difference in AFs (or refund the full CSR and charge the full CSP AF)? If it is past 60 days, will they prorate the difference?
I saw that they're prorating the AF if you've paid it on the CSP and are upgrading to the CSR, and I was wondering if the same was true going the other way and if it is true, is a time limit.
